34 pict 3 idle jet size{{ keyword }}

), Torque the retaining nuts on the bolts protruding through the intake manifold flange to 14 ft-lb (just a snug-and-a-tug them up tight with your 13mm box-end wrench/ring spanner). Just start off with a larger than normal size (150 maybe) and use the screw to increase/decrease the actual hole size. EMPI Performance Products Pict-3 34 Direct replacement for the original Solex 34PICT3 - comes with 70 Air Jet - 127.5 Main Jet - 55 Idle Jet SO-100 $ 28.62 Solex Pict-3 28/30/31/34 Rebuild kit G1134 $ 3.25 Gasket - Flange Gasket - ID 1.540 98-1288-B $ 189.95 . If you can't find one at about 125-130Z, try a smaller one, say 110Z. Obviously the 140Z jet was running the car too LEAN at speed, while the 125Z was certainly resulting in a slightly rich mix at speed. But optimum performance and MPG will be achieved when you use a wide band and tune the carb for 16:1 A/F on cruise, and 13:1 over 1/2 throttle. and 34-3 carb. The carburetor has a 55 idle, X125 main and 125 air correction jet. body (5). 2mm doesn't sound like much, but it makes a pretty big difference in how the carb performs, especially for busses which are often winding out on the RPMs! Note: Some people use a 13mm S-wrench (ring spanner) to remove the front nut. You also set the accelerator pump for maximum stroke when using the 009. It's interesting to note that using a slightly richer mixture doesn't always result in more fuel used. Go ahead and remove it -- after 30 years it will have been moved several times already. if you look around to really get it right on! In other words, it's extremely crucial for in-town driving. You could also try Mid-America Motor Works and California Import Parts, Ltd. if you have trouble finding them. You can also get detonation (pinging/knocking) if the engine gets too hot. Once all together, retune the carbs (mixture and idle speeds) as per standard VW tuning methods. Secure the fuel hose to the inlet nozzle on the carburetor with a new hose clamp. I couldn't find it in any book. Any auto supply store can sell you a little T-shaped adaptor that will fit on the terminal, with three "wings" (if you will) to which the three black wires can be attached. almost all the way to the top.-the idle 'cut off' solenoid clicks repeatedly when tested. The 34PICT normally has a X127.5 main and a 140Z or 170 air correction jet. Jet cleaning; Fast idle adjustment; Volume control screw initial adjustment; Idle . Carburetor Cleaning If you try removing the idle shut-off valve and the air correction jet (the brass bolt head in between the float bowl and the main throat) and the idle jet itself, and then blast air through the passages in both directions, that might get it. It's actually much easier to do if you remove the top of the carburetor and the float. Our 74 Super has a tube running from the 34 PICT 3 down, and is . Remove the main jet (as above) and blow through it (check for crud in the float bowl at the same time). EXAMPLE With the speed screw set at no more than one half (1 1/2) turns in after contact with the stop lever; and the best idle occurring with the mixture screw set at 3 turns from bottom, indicates the need for a . Items that are not expected to be restocked within 2 weeks WILL BE AUTOMATICALLY CANCELLED. There are three (or four) removable jets. Once you have those two sorted, then try a faster run and from 60 try flooring the throttle - if you get a good smooth response the air correction jet should be OK, but if it tends to stumble a little or feel breathless, then either the main jet is a little small or the air correction jet is a little large. This is what causes the visible rich condition, and confirms the need to increase the jet size. Jetting was tweaked over the years for various carbs and territories. Have a look at the size stamped on it too. I have a 52.5 idle jet in it, so it took about 4 1/2 turns to get max rpm ( thru a tach on my timing light). This will richen the mixture and help eliminate any 009 flat spots. If you live at altitudes above 5000 feet, you also have to consider that, as high altitude results in the engine running rich (less oxygen in the air but the same fuel flow through the carburetor). Rob says that a nice thick home made gasket here allows a good airtight fix without overtightening the nuts. This carburetor will NOT work well with cams with over 270 duration, (same as the stock 34-3 carb). Once the jet is loose it sort of falls on it's side, so then I use the screwdriver to nudge the jet out along the trench to the plug hole in the side (rather than using needle-nose pliers). The air corrections I have are 125z, 170z and in the carburetor a 135z. If you have a significantly larger idle jet (e.g., 70 or so), John Connolly recommends going down until you can not get a good engine response with the mixture screws anymore. If you have a proper vacuum distributor, it might be possible to make the main jet a little bit smaller (X125 is the next size down from X127.5), but this will not make very much difference in the fuel consumption. A sooty plug means the idle jet might be a little large. On the twin port engines, it has to be used with a 30/34 adaptor, since the twin port manifold has a larger mounting flange than the single port manifold. Note: Regarding "drilling out" the main jet, please see our article on Tuning the 009 Distributor/ Remove the brass plug with a hex head on the left of the carburetor -- bottom of the float bowl (all the fuel in the carburetor will rush out). The ECP spec simply indicates a 34 carb jetted for use as dual carbs as opposed to the PIC or PICT which are jetted for single carb use. That terminal on the coil is just a convenient place to obtain power to these components. When using the 30PICT or H30/31 carburetor on a twin port manifold and any vacuum distributor, change the jets to X125 or X127.5 main, 55 idle, and leave the air correction at 125Z. The proprietor of Aircooled.Net thinks the main jet is a size X130, and the idle jet is size 50.) See our Carburetor Overhaul Procedure. Try the X125 main before you try the X127.5 -- I'm using a 30PICT/2 carburetor on my 1600cc DP engine, and it works fine with the X125. Golf Mk1 > Volkswagen Workshop Manuals > Power unit > 34 PICT, Keihin carburettor and ignition system > Mixture preparation carb. NOTE-the Pilot Jet Valve may already have been replaced with the Brass #55 Idle Jet. If you are using a 009 distributor with a 30PICT carburetor on a 1600 cc DP manifold, the main jet should be X130 or X132.5 and the air correction reduced to about 100Z. There are a few fuels which have up to 85% ethanol in them (E85). Solex 30 PICT-3, 34 PICT-3 and 34 PICT-4, remove the air bypass screw. Setting the idle screws (B): Tighten the screw until it touches the carburetor lever. Ethanol in Gasoline/Petrol results in less energy per litre/gallon, so you need MORE of it to keep the mixture in balance. Details. When using the 30PICT or H30/31 carburetor on a twin port manifold and any vacuum distributor, change the jets to X125 or X127.5 main, 55 idle, and leave the air correction . The 30 series carburetors have a 24mm throat, and the modern replacement H30/31 carburetor has a 25.5mm throat. Our ability to respond to emails is greatly hampered by being under-staffed during this downsize transition time. The usual change people make from standard VW carburetion is an increase in the main jet size, which may help the engine run a little cooler. Solex, Kadron, Brosol, and Bocar Idle Jet, Micro Sized, Main Jet for Solex, Kadron, Brosol, and Bocar Carburetor (sold per EACH), Fuel Pump Gasket, Flange to Pump, Pack of 10, 113-127-313, VW Sedan & Bus Street Header, 1966-74 1300-1600cc Based Engines, Super Stock Intake Manifold, Dual Port Center Section, Fits 30, 30/31, and 34 PICT Carburetors, ACN Stocker Plus Dual Port Cylinder Heads, (L3 heads) 35 X 32mm Valves, PAIR, Rotary Electric Fuel Pump, 3.25 psi Low Pressure, 9mm Fuel Filter Inlet and 7.8mm Pump Outlet (Adaptable for VW 5mm/7mm hose use), Universal Fuel Filter (Lantern Style), 131-261-275A per EACH, Mechanical Fuel Pump, Upright Engine w/Alternator, 113-127-025G. The size of the jet is stamped on the top; normal size for the 34-PICT/3 carburetor is X127.5 (1.275mm diameter hole). It this case you would definitely need to reduce the main jet size to say the size 122.5 or the 120. Now unscrew it exactly 2-1/2 turns. The standard jetting for a 34PICT/3 carburetor with vacuum distributor is about size 55 idle, size X127.5 main, and size 100Z-120Z air correction jets. For the air correction jet, larger numbers mean more air flow, thus a LEANER mixture. Carburetor Removal Unscrew this bolt and look at it -- if there is a jet screwed into the bolt (older models), you can deal with it in hand, so to speak. This will have the main jet supplying the fuel, and read the plug again. Soot will indicate the main jet is a little too large. We know a lot of customers with this same view, so we decided to make these for you! SUPER-STOCK-34-3. Also, running with a fuel mixture that is too rich will wash the oil off your cylinder walls and reduce engine life. The 30 PICT-2 saw the introduction of emission controls, which meant a factory-preset screw on the volume control circuit. A 44 IDF would need a 55 idle jet, and a 48 IDF would need a 60 idle jet. I also have a stock carb rack but it appears to have water damage and one or more carb is seized. The idle cut-off valve sticks out the left side of the carburetor on H30/31 and 34 sries carbs (but on the right side on 30PICT series) and has an electrical connector on the end. The back one (pilot?) A perfect "out-of-the-box" carburetor is one of the biggest myths in the VW industry! Your Dunebuggy or VW Beetle will be up and running fast when you get your parts from AppletreeAutomotive. This little ball bearing MUST be in place. Check the jets in the carburettor - if you have a vacuum distributor (you didn't say which sort you had), then the 34PICT/3 carburetor should have a 55 idle (right side of the carburetor. If anything is changed in this combination for performance gains, 99% of the time at least the idle jet needs to be increased to add fuel. Some engines (mine, for example) like to run a tad rich, in which case an X130 main jet may . If the idle RPM peaks at 2-3 1/2 turns out, you're OK. If it is any lower the choke may be staying on too long, or it may be stuck on and won't open at all. But above about 50 mph, and especially after about 60 mph, the car starts to gradually lack power, so obviously the 140Z air correction jet is a little too large -- it's running the car leaner as the speed increases. Choke vacuum diaphragm (38) on a 1776. All the plugs look the same -- black and fluffy, telling me a rich condition. Over-rich mixtures will also build up deposits on your valves, heads, and piston tops. If you're still looking lean, go to a 132.5. The power jet counters the leaner condition at higher rpms, richening the mixture back into balance again. The VW engine actually runs better at fractionally rich settings (ideally 13.8:1 rather than 14.5:1 according to Bob Hoover). You can find 57s, etc. This will tell you if it's running rich or lean at speed and then you can set the air correction jet accordingly (smaller air correction means richer mixture - is delivers air so it works the opposite to a main jet. Also make sure the accelerator pump is set for full squirt, and is squirting straight down the throat past the opening throttle plate - not splashing on anything on the way. If it seems a little rich at higher speeds (plugs sooty after a plug read) then try the 130Z air correction jet. Checking and adjusting cold idle speed =>page 22-53 Throttle valve positioner Venturi size refers to the narrowest channel in the carburetor throat. Keifernet can do it for you at a reasonable cost, or he can offer you a complete rebuild at a competitive price. The jet has a slot in the back so it can be loosened with a screwdriver through the hole where the plug was. You can email to cancel un-shipped/un-paid items at any time as long as they are not direct-shipped, special order or made/machined-to-order. This jet is critical to engine flexibility and economy. I find it much easier to just use a regular 13mm box-end wrench (ring sopanner), as getting the S-wrench on and off of the nut is very difficult (walls on the box (ring) end are too thick). Make sure the old one you took out stays in good shape so it can be reused. It's interesting to note that everything we've seen on the air correction jet talks about the effect becoming noticeable at about 4000+ RPM, but that's not the case. Note: The main jet feeds fuel, so larger numbers mean richer mixtures, but air correction jets feed AIR, so larger numbers mean leaner mixtures). I rebuilt the carb that was on it, as well as a. swap-meet spare, before installing the engine this spring. 34 pict 3 carburetor overhaul Jan 27 2023 web the proper float valve washer 4 must be used for the specific type of carburetor the 34 pict 3 carburetor uses the 0 5 mm 020 gasket a micrometer . It provides fuel at low medium revs too, so if it's not working you'll get a rough idle and lean mix at lower revs. The exhaust system peashooters started turning black inside as soon as I put the larger jet in. Peugeot 205 Manual . All this indicates a good mixture and correct heat range. The 1600cc DP can flow more air than the 1600cc SP and smaller engines. Look down into the top of the carburetor to make sure that the screwdriver is squarely in the slot in the jet and that the threads line up squarely, then just screw it in (the small screw driver sits deep in the slot in the jet and helps line it up). The carburetor idle circuit controls how much fuel you have at idle. Thus a size 55 idle jet is 0.55mm, size 125 is 1.25mm, etc. Air correction jets are harder to find. When you work out the area of the hole in each jet, the steps are roughly 2% increase in fuel flow for each size up (X125 to X127.5 for example). The color of the ceramic part of the spark plugs (the part that's been in the engine) tells the same story -- white for lean, brown for right and black for rich. For example, a 40 IDF would need a 40 x 1.25 = 50 idle jet. While it is necessary to enrichen the fuel mixture when running an 009 distributor, you don't want the any richer than necessary since it will use more fuel. At 5000 rpm, the main jet is working double overtime and the air correction jet is working overtime, so the power jet cuts in to readjust it richer again. The /4 version was used in California and had additional features to reduce emissions. Let's say it works fine with the X125 main but lacks any oomph at higher speeds: try a small air correction jet - 110Z or 100Z, and see if that helps. If you have a 009 (centrifugal advance) distributor, you may find that the spark plugs still seem a little dry/burnt looking at medium speeds , or the car lacks acceleration in the mid ranges. More throttle does make it go away. If the problem occurs at higher RPM (2500-4000), then you need to richen up your main jet. Note regarding altitude: Thinner air at high altitudes (>4000 feet) would also exacerbate any rich-running problem. Recommended sizes are given in this article. The If it takes 4 1/2 to 6 turns to peak, go up a size or (1/2 size if you. You'd think the jet sizes would follow the capacity more closely, but they don't. I've been running my '68 Bug with the X127.5 main jet in the smaller carburetor, and he's running a tad rich. In most cases you can just leave the power jet alone. Then tighten further according to the chart. Bentley (page 20 of the 'fuel' section -- table of 'carburetor setting and jets') says the X130 was normal for '71-'72 34PICTs, and X127.5 was normal for '73-'74s (non-California models). Carburetor Disassembly I have recently rebuilt a 34-PICT 3 for my bus with a S.B. . Note: Compare the new float valve with the old one. A clean plug with a light grey/tan look means the mixture is about right. Replacing the main jet in is super easy -- just put it in the hole in the side of the carburetor, then put the screw driver in after it and slide it along the 'valley' that runs across the bottom of the float bowl. See our. I played with the timing, the volume screw, almost everything, I even found a X120 main jet and tried that as well, but she's still failing. 55 idle is fine. Main jet plug seal (15) I have checked my idle timing with the vacuum line disconnected and plugged, also checked high idle (5 @ Idle & 32 @ High Idle). Note: Dave found that NONE of the several top-to-body gaskets provided in the kit was the right size or configuration for his carburetor (he was possibly sent a kit for the earlier series carburettors). The larger 34PICT carburetor should have the larger X127.5 main jet, and since the larger 34PICT carburetor doesn't have the extreme airflow with a 1600cc DP engine that the 30PICT carburetor does, the over-rich problem is reduced, so you use a SMALLER air correction jet - less correction is needed. There is an pilot (idle) jet on all carburetors too - these are normally left at 55 for most carburetors (28, 30, H30/31 and 34 series), on any engine size (since it's only feeding the engine at small throttle settings anyway). The main jets also fit EMPI and Brosal Kadron 40/44EIS Carburetors. To summarize: idle jets operate from idle to 2500-3000rpms or so. . Note the three black wires leading from the positive terminal on the coil -- one to the backup lights, one to the automatic choke, and one to the idle cut-off jet. On the premise that the 1600cc engine likes to run just a tad rich, many people will change out the main jet for a size X130. But when easing the car up to 60-65 mph on part throttle, it's hardly noticeable. Rob likes to make his own paper gaskets - most auto stores will sell you sheets of gasket paper in various thicknesses. Regarding the 1776cc engine: the stock 34PICT/3 carburetor with a fractionally larger main jet and a fractionally smaller air correction jet to suit the higher air flow being asked of the carburetor should suit nicely. All Solex carburetors tend to run lean at high power settings (high rpm and open throttle). 3. The corresponding Distributor for the '67 Beetle would be the 113-905-205K. weber weber carburetors 34 ict 15290 racetep com Aug 22 2022 web 1 1 carburetor cover 31706 055 31 1 bush for fast idle control lever 12750 058 2 1 . Air is much less dense than gasoline, so that makes sense. And I have the by pass air cut off valve (12V thing) on the left side (as same as on the 30 PICT-3, which I have seen on pictures in books, but the by pass air cut of valve were always shown on the right side). Fillister head screw and lock washer (upper Obviously it also fits all Dual Port Intake Manifolds, and we've had excellent results from these quality carburetors (Unlike the Chinese Copies!!!). Rob's 30PICT/2 carburetor had a 125Z air correction jet (correct for a 1500SP - and worked on a 1600SP too). As we learn more, we will include it here. I think the original idle jet was a 50, but the replacement jet orifices (orifii?) Venturi Size. A loss of power is the result -- about 58hp instead of 60hp. Rob provided further explanation: The idle circuit is behind the main jet - the fuel flows THROUGH the main jet to get to the idle circuit. For 1600cc engines, use an X130 main jet. The 34PICT/3 carburetor is usually used on 1600cc or larger engines. Regarding fuel consumption as a function of jet size -- The 1600cc Beetle should get about 10-12km/l (24-28mpg). In addition, if you have a problem with a 55/60 idle jet, and you have the right main jet, and still have a hesitation regardless of accelerator pump adjustment, you need to play with your idle air bleed (what the fuel from the idle jet mixes with). We need to do some research regarding the adjustable main jet. Free shipping for many products! Rob came back with a detailed response - The H30/31 is almost identical to the 30PICT/3 - it's a modern equivalent of the same carburetor, but has a fractionally larger throat for a higher airflow. Great for that SLEEPER LOOK! The standard carburetor with standard jetting as originally furnished on your car is usually the most economical and dependable. The idle cut-off valve receives power from the positive (+) terminal on the coil (#15) -- see the schematic which shows this wiring arrangement. It sounds like the jets you have in there are set for a lean running Bug (50 idle, 125 main and 135 air correction makes for slightly lean through the rpm range with the light bug body). For the 1600cc engine, you need more fuel flow, so a larger X127.5 main jet and 100Z or 120Z air correction jet are needed. 2-F7 emulsion tubes for the IDF. There is enough variation in fuel types, wear and tear on engine and carburetor, altitude and so on that you might need to experiment a little. Then remove a spark plug and read it (see our Spark Plug Reading Guide). And fuels! Perform the Idle Adjustment and Timing procedures. Could you help me with the jetting? We have heard it said that the X130 (or X127.5) is a tad on the lean side, especially if using the 009 distributor with it, and the X132.5 gives a fractionally rich mix (which VWs have always liked better than lean). But engine sizes have much more variation, 1200cc to 1300cc is about 8% more, 1300cc to 1500cc is nearly 14% more, and 1500cc to 1600cc is about 7% more. Try to use the leanest main jet you can -- too rich will only result in the cylinder oil film being diluted more, and this means higher cylinder wear. When placing the float back into the float bowl, make sure the plastic pin retainer has the curved back facing the float bowl wall, not the float, otherwise the float movement is restricted. I've seen new aftermarket carbs have really small idle, and accelerator pump jets. Screw it in GENTLY until it bottoms. [3] The Volume Control Screw is the smaller of the two adjusting screws. We sincerely appreciate your patience while we are doing these site upgrades. It would be interesting to try using one an adjustable main jet, but there are some dangers too ? Orders are processed in the order that they are received and order fulfillment time varies. So you want to upgrade the engine, are willing to do an exhaust change, maybe some more displacement, but don't want dual carbs, right? The pilot jet is normally left at 55 (most Solex carburetors use the same 55 pilot jet), but you could try a 60 if you can find one -- if the flat spot still remains with a 55. If your car is having a problem with spitting/sputtering/cracking, this is an indication of the fuel/air mixture being too LEAN. Milease has increased by 90 miles per tank. And of course make sure that it's properly connected electrically to the connection on the coil where power is provided (the + connection) -- the lead can break off. With a leaner 140Z air correction jet in the carburetor) I got 11.6 km/l (27.5mpg US). . Special Instructions The smaller jets WILL NOT work with the 009 distributor. In the boxes of parts was a new manifold for the 34 Pict 3 carb. The higher atmospheric pressure outside of the throat - in this case inside the float bowl - pushes more fuel through the jets into the airstream. If it's not, the float bowl will overfill through the bowl vent down the throat of the carburetor, causing the fuel/air mixture to be WAY too rich - and of course the exhaust will spew out a lot of black smoke and the engine will not run. The VW 105-1 Air Correction Jet would be 125z. The air correction jet must be SMALLER to enrichen the mixture. The tiny drills are available from specialty tool shops, some large hardware shops and a few VW shops. The power jet is usually a size 65. The larger size 65 idle jet helped the 30PICT/3 and H30/31 carburetors overcome the very lean main jet at idle and low speeds, and thus help to reduce the "bogging" problem. Our last contact with Keith was some years ago. Do you know what size high speed jet you have? See our Accelerator Cable Adjustment Procedure. With lean jetting you are likely to need more throttle and have slightly worse fuel economy - using the slightly richer settings I'd suggested above will give you a little more power and a cooler running engine, so hopefully fuel economy will improve a little, but don't expect too much - fuel economy with the heavy Type 2 body is never very good. ). Another question - The car runs terrible but it runs. Use a steady throttle - minimum acceleration. Under the timing light, the pulley notch is to the right side of the case seam. The fiddly bit is pulling the jet back through the hole. 34 PICT-3 carb, SOLEX 34MM ; Fitment: Carburetor Fits For any 1600cc VW Air cooled Type 1 engines,such as: 1971-1979 Volkswagen Beetle, 1971-1979 Volkswagen Super Beetle, 1973-1974 Volkswagen Thing, 1971-1974 Volkswagen Karmann Ghia, 1967-1973 Volkswagen . Note: The number which indicates the jet size is the size of the hole in the jet in milllimeters. (Adapted from John Connolly's article on How to Jet Your Carburetor. Note: It is very important that you install the correct needle seat gasket. Which one is which one? Since Aircooled.Net has no control over product installation, we will not be held liable for any consequential costs or damages associated with products purchased. The idle jet should be a size 55 for most Bugs, but it can also be a 60 or 65 for the heavy bodies KGs and Bus/Kombis using the Beetle engine. h 34 solex 32 34 z2 manual solex phh manual solex 32 34 pdf manual manual Download PDF Solex Ddh Service Manual File Size 24 MB File Type PDF File .

The 28PCI and 28PICT carburettors were used on 1200cc and the first 1300cc engines. The idle jet is usually a size 55 (when the main jet is normally a size X125 or X127.5) but it might be a size 65 if the main jet is a X122.5 or smaller. The modern H30/31 carburetor replaces the 28, 30 and 31 series carburetors and can be used on 1200cc, 1300cc, 1500cc and 1600cc engines with appropriate jetting. Well, if the fuel/air mixture is too rich, the extra fuel will wash the film of oil off of your cylinders and wear out your pistons, cylinders, and rings quickly. Turn the Bypass Screw (the larger one) out a couple of turns, to get things started. "N" on the schematic is the coil. Then if you need a fatter idle go up to 57.5, then 60. Sent from my SM-G930F using Tapatalk Note: A cheaper alternative to buying a new carburetor is to have the carburetor rebushed. *** Supply-chain disruptions have hampered our ability to acquire/restock items reliably, and a lack of backorder ETA information is the frustrating "new normal" for our hobby. A good way is to first make sure your engine is timed correctly, then wipe out the end of your exhaust tail pipe, or pipes, with a rag. Main jets are primarily from 2500-4500rpms, and Air jets affect the engine from 3500/4000 on up. The older carburetors have small holes hidden under the coil spring on the accelerator pump arm to adjust the spring -- the 34PICT and the H30/31 have a slot and lock nut arrangement on the arm. There is a Mexican Solex 30 Pict-1 replacement Carburetor. the 127.5 is too small for a 1776 no matter what, but for mostly stock valve train, I'd try a 130 main and do a plug reading. Using a new gasket, install the carburetor on the intake manifold flange. All information should be verified prior to use. Adjustment directions are given below. carburettor data 1124 cc models Venturi diameter 25 mm Main jet 127 5 Idle jet 48 Air correction jet 175 Emulsion tube EM Enrichment jet 50 . Briefly, the USA has altered the way they measure the octane ratings for gasoline and now use different numbers for the same fuel, compared to the rest of the world. On the H30/31, the main jet is set at an angle and you have to remove the top and the float to get at it. Our site uses advanced code and encryption that is not supported by Microsoft's Internet Explorer Browser. For information -- the 1200cc engines originally came with a 28 PCI or 28 PICT carburetor, both of which have a 22mm throat. The air correction jet doesn't affect idling very much since it helps control the mixture at higher rpms, but worth a look to see if you have a fuel blockage problem in the carburetor. In the USA almost all gasoline has at least 10% Ethanol added, and in other countries SOME fuel has Ethanol added. Jetting was tweaked over the years for various carbs and territories, links, forums and., heads, and he 's running a tad rich, in case...
