34 pict 3 idle jet size

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. As indicated previously, the VW engine actually runs better at fractionally rich settings (ideally 13.8:1 rather than 14.5:1 according to Bob Hoover who did lots of testing), but they are usually jetted a little leaner than that, so the X127.5 is really a minimum jetting for the 1600cc engine. Automatic Float pin retainer (7) On the /3 and /4 carburetors - it looks like a bolt with a tiny silver plug in the center. So be sure to remove the gasket and store it carefully. were visibly larger in the new jets than the old ones. . The fuel flow through each jet is determined by the airflow which creates a low pressure area near that jet. nomenclature and part number (referring to the exploded view). Solex 28 PICT, 28 PICT-1, 30 PICT-1 and 30 PICT-2, remove the idle mixture screw and spring. Many thanks, John!). 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. If it takes 4 1/2 to 6 turns to peak, go up a size or (1/2 size if you. 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 . Most gasoline in the USA now has at least 10% Ethanol added (E10), and in other countries, SOME fuel grades have 10% ethanol added. 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. A sooty plug means the idle jet might be a little large. This jet helps mix the fuel when the throttle butterfly is part way open, and so if you make it too big, it will let in too much air, and the engine will hesitate because of that. 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. 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 the plugs look the same -- black and fluffy, telling me a rich condition. AU $0.86 (approx 0.48)Australia Post International Standard. valve - idle cut off (30pict-2,3) 5. plastic cap 26. plug - av x. fuel jet 6. spring - throttle return 27.

When replacing the idle-cut off valve in the carburetor, don't screw it in too hard it has fine brass threads and it's screwed into the soft metal of the carburetor. Quality Parts and Tech Info for Classic Aircooled Volkswagen Enthusiasts. Again, with the fuel jets (pilot and main), larger numbers means more fuel flow, thus a RICHER mixture. 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 carburetor will NOT work well with cams with over 270 duration, (same as the stock 34-3 carb). None of these tests are definitive - just indicative. Could you help me with the jetting? We have had great results with these factory bench tested carburetors. For a 1600 KG with 34PICT/3 and vacuum distributor, I'd suggest a 60 or 65 idle jet (a 55 idle jet is used for the bug but the heavy bodied KGs and buses used larger idle jets), 127.5 main, 80 or 100 air correction jet (80 makes it run a little richer in the mid range) and a 65 power jet. Main jet sizes run through a range from X110 to X150 (1.1 - 1.5mm diameter). Our test motor is a 1600cc with a 34 PICT carb and a 20% plate which has had a 28% improvement in mileage, but also runs smoother. If that's the case you need to make sure the idle cut-off solenoid is working (a nice click when you touch the wire on the connector) and that the idle jet (which it screws into) is not blocked. Solex 30 PICT-3, 34 PICT-3 and 34 PICT-4, remove the air bypass screw. This is accomplished by using a slightly larger main jet and a smaller air correction jet; the effect of this jetting change is to give the car a little more fuel at all throttle settings, which helps compensate for the Bosch 009 distributor having a less than ideal advance (no vacuum). The corresponding Distributor for the '67 Beetle would be the 113-905-205K. The exhaust system peashooters started turning black inside as soon as I put the larger jet in. mains: 120, 130, 135, 145. air jets: 160, 170, 180, 185. I managed only 22 mpg on a highway (around 50-55 mph), and 19 mpg when I was driving around 60-65 mph. 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. Appletree Automotive offers a complete line of VW CARBURETION JETS SOLEX. This will have the main jet supplying the fuel, and read the plug again. Dave replaced the main, idle and air correction jets so he knew what he had. You may have to get creative about how you attach so many wires to the single terminal on the coil. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023. 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. 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. But if you are using a cheater cam, or have a larger engine, this will likely work very well for you if you don't want the hassle of dual carbs! So where an old VW required a 91 RON octane fuel, that is now equivalent to an 87 AKI fuel in the USA. Use a steady throttle - minimum acceleration. Useful experiment anyway.

The air correction jet prevents the mixture going over-rich at high rpm (again, smaller numbers means richer for this jet). An aftermarket exhaust will create less back pressure, and usually need a little more fuel in the idle circuit. Rob responded - If you still have a vacuum distributor - yes. 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. The 1600cc DP can flow more air than the 1600cc SP and smaller engines. Screw it in GENTLY until it bottoms. Regarding fuel consumption as a function of jet size -- The 1600cc Beetle should get about 10-12km/l (24-28mpg). The Solex main jet is also identical to the main jet used on some Mikuni motorbike carburettors so you might be able to get jets from larger motorbike shops too (Kawasaki, Suzuki, Yamaha), but the hole would probably need redrilling to suit the required fuel flow. We can only give a guide here, as engine age, type of fuel, carburetor wear, etc. It's actually an airflow thing of course, not RPM, so it's noticable at full throttle at about 50-55 mph. 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).

It should not be possible to blow air through the valve while the needle is pressed lightly onto its seat. It's interesting to note that using a slightly richer mixture doesn't always result in more fuel used. See details. Note: Do not soak the choke heating element, pump diaphragm, float, vacuum diaphragm, or any other rubber or plastic parts in carburetor solvent. Be careful pulling it out -- it's about an inch long. Make sure your regular tuneup things are in order. Lastly, you have emulsion tubes to change "where" it's rich, lean, etc. A 44 IDF would need a 55 idle jet, and a 48 IDF would need a 60 idle jet. Volume control screw O-ring (18) We are able to serve the many aircooled VW fans who rely on our services most effectively via Online Ordering and via Email. 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. 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. I also adjust my accelerator pump after getting it to idle good. Do you know what size high speed jet you have? ), 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). 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.

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. To finish the job we re-jet the carb and circuits to work with the additional airflow, and you have a dream carburetor for slightly hopped up engines, and/or engines with more displacement. Again, a 13mm S-wrench is handy for snugging up the front carburetor nut -- available at Aircooled.Net. The standard jetting that the 30PICT/1 & 2 carburetors came with is size X122.5 or X125 main, size 55 idle, and size 125Z air correction jets. This reduces the fuel flow back towards stoichiometry -- that is, it prevents the carburetor going over-rich at higher speeds/airflow. The following topics are discussed in this article -. The air correction jet starts leaning the mixture to bring it back into balance, but as the rpms (airflow) rises to near the maximum for that carburettor, the air correction jet works too well, running the engine lean. Be careful that you don't tighten these nuts too much -- you may strip the stud out of the base of the carburetor. Immediate shipment of requested products is NOT guaranteed.

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. This gasket sets the fuel height in the float bowl; erratic behavior may result if the gasket is not correct. Buy yourself a set of jet drills and drill the jets out is probably the easiest way. So a 34PICT/3 carburetor with an 009 distributor should be jetted with an X130 or X132.5 main jet, and an 80-100Z air correction. 34 PICT Carburetor Combination.

Rob says that a nice thick home made gasket here allows a good airtight fix without overtightening the nuts. The try the same test at a higher speed - a steady 55-60mph. 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. 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. Our 74 Super has a tube running from the 34 PICT 3 down, and is . Details. 1975 GL1000 Restored (sold) 1983 GL1100 Custom (sold . That means that the jetting requirement for any VW using ethanol-added gasoline/petrol is different to those using straight hydrocarbon gasoline/petrol. 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. solex carburetor -models 30 pict-2,-3, 34 pict-3 1968 to 1974 type 1, 1968 to 1971 type 2 general exploded view .

Discussion in 'Mech Tech' started by low_light_craig, Jun 9, 2017. 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). 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). *** 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.

Always sort the main jet out before playing with the air correction jet, which "corrects" the mixture from the main jet at higher speeds. To explain, the main jet supplies the fuel, and it supplies too much as the rpms increase (a function of the increasing vacuum in the main venturi). "Leaving it alone" is fine for a new carburettor but silly when the engines are all at least 30 years old and in different states of health. We need to do some research regarding the adjustable main jet. So how do you know which to use? Location: Miami. I would think you would need a .55mm-.60mm idle jet, and a .60 pump jet.

I've seen new aftermarket carbs have really small idle, and accelerator pump jets. Price: $ 399.95. The X127.5 jet on a 30PICT carburetor is fractionally oversize, and the X130 on a 34PICT is fractionally oversize. Discussion in 'Mech Tech' started by low_light_craig, Jun 9, 2017. low_light_craig.
