Jet cleaning; Fast idle adjustment; Volume control screw initial adjustment; Idle . The selection of main gas and air correction jets is determined by venturi size. Others are upset by a backfiring, or smoke belching monster. The air correction jet prevents the mixture going over-rich at high rpm (again, smaller numbers means richer for this jet). 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. Now I have installed a newer Solex Brosol 30/31 carburetor (the Brazilian one), in good shape. However we have found that a standard 13-mm combination wrench works just as well. So VW chose this configuration. If the idle RPM peaks at 2-3 1/2 turns out, you're OK. 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. Air is much less dense than gasoline, so that makes sense. 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. If this is the case, try a larger size main jet -- size X127.5 1200/1300/1500cc engines. Seller pays for return postage. . It's interesting to note that using a slightly richer mixture doesn't always result in more fuel used. The jet has the size stamped on it, which you may or may not be able to read without a magnifying glass.). You might want to drop a pilot jet size. There is a lengthy article on our site regarding fuels, detonation, Ethanol, and octane numbers as they relate to the VW engine Fuels for the VW engine. Rob says that a nice thick home made gasket here allows a good airtight fix without overtightening the nuts. The VW 105-1 Air Correction Jet would be 125z. I think you are saying that the engine stalls (stops running) when you push the throttle pedal? Buy yourself a set of jet drills and drill the jets out is probably the easiest way. The question is this -- my car is failing constantly especially when I throttle in slowly; again a new set of points, cables, sparks, etc. 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. Use stock vacuum line from air-intake #4 for CDI control unit. That means that the jetting requirement for any VW using ethanol-added gasoline/petrol is different to those using straight hydrocarbon gasoline/petrol. Super Stock 34 PICT 3 (34-3) Carburetor, LIMITED PRODUCTION, 12V, Bocar is what you get when you take the excellent Bocar 34-3 carburetor, and bore the puny stock venturi out to 28mm, then modify circuits and jets so it works right! The carburetor idle circuit controls how much fuel you have at idle. Main jet should be around the 130-135 area. 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. In both cases, when running the 009 distributor, set the accelerator pump for maximum squirt. It worked quite well, although the idle wasn't very accurate. DP case, 1641 P & C, w/ Scat C25 Cam, & stock heads. Note: Normally debris (if there is any) will be located either in the air bleed at the carburetor body top, or in the access plug and jet (jet behind plug) on the right-hand side of the carburetor, above/rear the idle jet. I rebuilt the carb that was on it, as well as a. swap-meet spare, before installing the engine this spring. Sent from my SM-G930F using Tapatalk by vwlover77 Fri May 05, 2017 6:58 pm. I have lowered the fuel pressure down to 2.5 psi and checked the float bowl fuel height. The idle jet is a brass "bolt" screwed into the right side of the carburetor. If it takes 4 1/2 to 6 turns to peak, go up a size or (1/2 size if you. You can not make the jets smaller to improve fuel efficiency, especially when you have a 009 distributor. . The power jet is needed to correct a tendency for the air correction jet to work TOO well at max airflow - it leans the mixture off too much and the power jet corrects this. If the idle cut-off valve fails in the shut position, the car will still run (roughly) on the main jets but will stall as soon as you take your foot off the throttle. If you don't have a compressor, talk to Santa Claus!

Rob responded - Yes, that sounds like a rich mixture. Actual product may differ in appearance. The fuel flow through each jet is determined by the airflow which creates a low pressure area near that jet. 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). All the plugs look the same -- black and fluffy, telling me a rich condition. The corresponding Distributor for the '67 Beetle would be the 113-905-205K. 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. Some of the replacement carburetors (H30/31 and 30PICT/3 maybe???) 21.00 (Excl VAT) 25.20 (Incl . Note: Dave found that none of the gaskets in his kit fit his carburetor. That terminal on the coil is just a convenient place to obtain power to these components. With the idle cut-off valve working correctly, hot spots in the cylinders don't occur as readily, since there is no fuel available to keep the engine running once you turn off the ignition. Take the car for a run at a modest speed - say 35-40mph. Remember on the 34PICT-3 the idle jet affects drivability and power up to about 2,000 rpm when the main jet takes over. Checking and adjusting cold idle speed =>page 22-53 Throttle valve positioner Aircooled.Net has them, and I think Gene Berg in the US has them too. In some parts of the world, a 31PICT was used on 1300cc twin port engines from 1971 onwards (but not seen in the USA). The speed of the engine (RPM) when it's doing this tells you which jet you need to change. We need to do some research regarding the adjustable main jet. almost all the way to the top.-the idle 'cut off' solenoid clicks repeatedly when tested. Carburetor body-to-cover gasket (6) The idle jet sits in a protrusion running down to the bottom of the carburettor, and the power jet sits in a protrusion running up to the top of the carburettor, so it's easy to tell which is which. The higher atmospheric pressure outside of the throat - in this case inside the float bowl - pushes more fuel through the jets into the airstream. 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. We sincerely appreciate your patience while we are doing these site upgrades. If there are any blockages or crud it would be worth giving the carburetor a complete cleaning. In most cases you can just leave the power jet alone. Golf Mk1 > Volkswagen Workshop Manuals > Power unit > 34 PICT, Keihin carburettor and ignition system > Mixture preparation carb. 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.

SOLEX 34 PICT 3 Carburetor Adjustment Procedures. Solex Carb Spacer for Alternator, 30 PICT Carburetors, 00-3245- Rob's note: When removing the main jet, I use a small glass jar (pickle or baby-food jar) to catch the fuel from the brass plug - I hardly spilled a drop (I just allowed the plug to fall in to the jar), and used the fuel to refill the float bowl later. Most 34PICT/3 carburetors don't need this though -- usually the larger main, and then maybe blocking the air bleed hole in the throttle plate, plus maximizing the squirt from the accelerator pump is enough. Which one is which one? 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. Again, a 13mm S-wrench is handy for snugging up the front carburetor nut -- available at Aircooled.Net. if you look around to really get it right on! I haven't run enough through the tank to get a real idea about consumption yet, but since I don't notice any huge difference in performance I'll probably be going back to the X125 soon. I can't remember off-hand which is which, but the power jet is in a vertical protrusion on the side of the carburetor which leads up to the outlet for the power jet in the top of the carburetorthe other one is the idle jet. Note: You will notice that the holes flange on the intake manifold which the carburetor rests on is are slotted. 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. Please only continue if you are prepared to be PATIENT. Use a steady throttle - minimum acceleration. 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. Most gasoline in the USA now has at least 10% Ethanol added (E10), and in other countries, SOME fuel grades have 10% ethanol added. Float needle valve and gasket (4 & 5) (See note below.) Useful experiment anyway. You . 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. 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. The 1600cc DP can flow more air than the 1600cc SP and smaller engines. We are now only fulfilling order requests only for items that we have in stock OR that we know can be acquired within a defined timeframe. 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. The extra advance helps reduce the 009 flat spot just a little. Solex 34 pict 3 jet size. 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. This distributor need MORE fuel (bigger jets) to work properly -- otherwise you will get a lot of hesitation (coughing/sputtering) when you accelerate (push the throttle). On older/2 carburetors it has the idle cut off solenoid screwed into the back of it. The other one (pointing straight out to the right side of the car) is the power jet, which feeds additional fuel at high throttle/high rpm. This carburetor will NOT work well with cams with over 270 duration, (same as the stock 34-3 carb). Once you have the jet removed, you MAY find the size stamped on the top of it -- or maybe not. 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. Setting the idle screws (B): Tighten the screw until it touches the carburetor lever. No blue fumes, so the piston rings are well installed. The air correction jet has the emulsion tube attached to it -- this "foams" the fuel before it's added to the airstream in the throat. Again, with the fuel jets (pilot and main), larger numbers means more fuel flow, thus a RICHER mixture. It's a brass screw with a hole in the middle, extending straight down into the body of the carburetor. 2060 Solex Pierburg Kadron idle jet; 2056 Solex Air corrector jet; S61634017 Solex Z1 - Z2 Float; Solex float PBIC PIBC PICT; Solex float PICT; 6200018 Solex Needle valve size 160 Fiat 124, Alfa Giulia; 52844 Solex Pierburg needle valve VW PDSIT PICT DIDTA DIS; Center-mounted carbs need a somewhat richer (larger) idle jet, since the carburetor is so far from the cylinders and the fuel condenses on the way there (so make sure your manifold pre-heater is functional). Now unscrew it exactly 2-1/2 turns. Then video is intended as an example.. Could you help me with the jetting? Venturi size refers to the narrowest channel in the carburetor throat.

Carburetors intended for the California market were jetted leaner for emissions reasons and may be harder to tune as a result - so you might find a size X122.5 main jet and size 140Z-170Z air correction jets. 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. 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).

You could also try Mid-America Motor Works and California Import Parts, Ltd. if you have trouble finding them. The air correction jet has to be the right size for the same reason. If you're still looking lean, go to a 132.5. Then remove a spark plug and read it (see our Spark Plug Reading Guide). The last three carburetors are more sensitive, and so the lack of vacuum advance on the 009 makes more of an impact. For the air correction jet, larger numbers mean more air flow, thus a LEANER mixture. Venturi Size. (Solex jets are marked with the hole size in mm, so a X127.5 jet has a 1.275mm hole - I'm not sure what numbering method Mikuni use). Do not allow cleaning solvent to come in contact with skin. Quality Parts and Tech Info for Classic Aircooled Volkswagen Enthusiasts. Classified ads, photos, shows, links, forums, and technical information for the Volkswagen automobile A loss of power is the result -- about 58hp instead of 60hp. 55 idle, 127.5 main.

Make sure this fits by entering your model number. I've rebuilt the carburettor, and it did not help. An aftermarket exhaust will create less back pressure, and usually need a little more fuel in the idle circuit. For information -- the 1200cc engines originally came with a 28 PCI or 28 PICT carburetor, both of which have a 22mm throat. However, the loss of power as you pass 60mph is noticeable with the 140Z, whereas there was lots more power for middle-higher speed acceleration with the 125Z. The effect is clearly noticeable from 3000 RPM upwards (just under 60 mph), and probably a little lower than that.

Contrast the Main Jet of the VW 105-1 for the '67 Beetle which would be120. The old one for a pattern and a sharp hobby knife or box cutter works well. *** 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. Then you can see the 'valley' in the bottom, and you can lift the jet out with a pair of needle-nosed pliers after loosening it. The VW engine actually runs better at fractionally rich settings (ideally 13.8:1 rather than 14.5:1 according to Bob Hoover). 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. The sizes are stamped in tiny numbers on the heads of each jet. Soot will indicate the main jet is a little too large. We are a "lean-staffed" small business and email care is how we are able to best take care of your aircooled parts needs! Both clearances are essential; If the accelerator pump linkage rubs on either end, the throttle lever will not be able to return all the way to the stepped cam, the result being an excessively high idle that cannot be controlled with the bypass screw. SUPER-STOCK-34-3. You also set the accelerator pump for maximum stroke when using the 009. With the air correction jet you have to go 3-4 sizes different to see a real difference, unlike the main jet where one size can make a big difference. I'd go for a 130 main. mains: 120, 130, 135, 145. air jets: 160, 170, 180, 185. If the valve sticks in the open position, the idle fuel circuit will remain open, so if the engine is still turning it will still draw fuel through the idle jet, resulting in running on if there is a hot spot in one or more cylinders. 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. 1975 GL1000 Restored (sold) 1983 GL1100 Custom (sold . .
