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. 55 idle is fine. Sounds like a good starting point! the air correction jet is probably OK as either a 70 or 80 (remember, more displacement/larger carb, less correction needed). A sooty plug means the idle jet might be a little large. 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. 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 . Except for the fact that it won't idle! Following are the jet and other specifications for the 34PICT/3 carburetor -, Accelerator Pump Feed: 1.3 - 1.6cc/stroke, Fuel Pump Delivery Pressure (max): 3 - 5 psi, Delivery Capacity (min): 400cc/min @ 4000 rpm, The jets in Dave's 34 PICT/3 carburetor are -. Our last contact with Keith was some years ago. If you look at the two jets you can see that the (angled) idle jet sits in a protrusion (channel) which continues downwards under the jet, towards the idle and transfer ports in the throat near the butterfly. 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. In these later models, you can easily change the jet with a medium screwdriver either with the top of the carburetor removed or with the carburetor completely off the car. But after November 15th, all still pending backordered unshipped items will be automatically CANCELLED **(except for any special ordered drop-shipped or made/machined-to-order items). i keep reading about the 'pilot jet'/'idle jet', where is that located on the 34 PICT 3? 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 idle jet is on the right side and the other jet there is a power jet (which only starts working at high throttle and high rpm). The main jet is accessed by removing the big brass bolt on the left side of the PICT carburetor, right at the bottom of the carburetor bowl. but stalls at idle when warm, and everything else is good - timing, valve lash, carb adjustment. Main jets are primarily from 2500-4500rpms, and Air jets affect the engine from 3500/4000 on up. "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. The 30PICT/2 carburetor has a fuel idle cut-off in the right side of the carburetor but the 30PICT/3 and the H30/31 should have an air idle cut-off in the left side for the carburetor (same as the larger 34PICT/3) -- that was part of the change to the /3 carburetor version -- moving the idle cutoff valve to the left side. The jets in Dave's 34 PICT/3 carburetor are - Main jet - X130; Idle jet - 55; Air correction jet - 80Z ~~~ Jetting With the Centrifugal-Advance 009 Distributor, The 009 centrifugal-advance distributor can not sense throttle position engine load, only engine revolutions, so it's not ideal in all circumstances, Changing the jetting in . I have main jets: X117.5 and X127.5 and as far as I remember currently in the carburetor is a X125. 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. Air correction 75 to 125 and these are changed. Many thanks, John!). CATALOG ERRORS: Although every effort has been made to provide accurate pricing and product technical and vehicle application information, THIS CATALOG MAY CONTAIN ERRORS (typographical, photographic, or informational). 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. 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). Another - You mentioned a bigger jet -- are they available? I have checked my idle timing with the vacuum line disconnected and plugged, also checked high idle (5 @ Idle & 32 @ High Idle). It's a complex problem that faces ALL open throat style carburettors. Automatic
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). 3. Note: Dave found that none of the gaskets in his kit fit his carburetor. The carburetor idle circuit controls how much fuel you have at idle. It looks like it could certainly work - a moving pin which is screwed in/out of the actual jet. 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). Reply to Phatman. I also have a stock carb rack but it appears to have water damage and one or more carb is seized. It worked quite well, although the idle wasn't very accurate. 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. If your solex 34 pict 3 starts and runs fine when cold. valve - idle cut off (30pict-2,3) 5. plastic cap 26. plug - av x. fuel jet 6. spring - throttle return 27. Our 74 Super has a tube running from the 34 PICT 3 down, and is . We provide the classic VW hobby with tech tips, project advice, and quality parts for VW Restoration, VW Performance and Custom Aircooled VW projects. I managed only 22 mpg on a highway (around 50-55 mph), and 19 mpg when I was driving around 60-65 mph. Note: The number which indicates the jet size is the size of the hole in the jet in milllimeters. All the plugs look the same -- black and fluffy, telling me a rich condition. 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. With the richer 125Z air correction jet I got 11.8 km/l (27.9mpg) -- no real difference. Be careful pulling it out -- it's about an inch long. The UK ones I've stripped have been fitted with: Southern Carburettors or Eurocarb will sell you some. 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. 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. Then if you need a fatter idle go up to 57.5, then 60. 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. The Power Fuel System Dispensing Nozzle for the VW 105-1 would be 0.50 with no check ball. any input would be much appreciated. 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. These carburetors come jetted "generally", and will bolt on and run. These plates provide restriction and also atomize the fuel/air mix better for greater fuel economy. Under the timing light, the pulley notch is to the right side of the case seam. Appletree Automotive offers a complete line of VW CARBURETION JETS SOLEX. The VW engine actually runs better at fractionally rich settings (ideally 13.8:1 rather than 14.5:1 according to Bob Hoover). All Solex carburetors tend to run lean at high power settings (high rpm and open throttle). to the back of the engine, in an angle) is a: g f 50 and the other: g f 50. Now unscrew it exactly 2-1/2 turns. The idle jet is normally a little larger when used with the heavy bodied Type 2 and Karmann Ghias - in a Bug you usually use a 55, for a Type 2 or Karmann Ghia use a 60 or 65this gives you a little more power at low and medium speeds. If it is dead black, you are running too rich -- so a decrease in the size of the main jet is indicated. (The jets are made in 2.5 increments, so it goes X127.5, X130, X132.5, X135 etc. An altitude of 5000 feet is roughly equivalent to a one size main jet difference. Sorry! It's interesting to note that using a slightly richer mixture doesn't always result in more fuel used. This means that the main jet is sized to the engine capacity, rather than the carburetor size, and X127.5 is the more common size for the 1600cc engine, rather than say the X125. We disassemble the carburetor, and bore the venturi to 28mm for more air! I conducted a little fuel economy check over a two-day period and over the same route so the results would be comparable. Carburetor Cleaning
The venturi sizes listed below are the sizes supplied by Weber in new carburetors. A clean plug with a light grey/tan look means the mixture is about right. -there is fuel in the 34 PICT 3 resevior. 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. For information -- the 1200cc engines originally came with a 28 PCI or 28 PICT carburetor, both of which have a 22mm throat. I have EMPI 34 pict 3 on GL1100 55 jet 130 jet idles 1000-1100. Milease has increased by 90 miles per tank. In other words, it's extremely crucial for in-town driving. The only way I can think of would be to solder up the hole and redrill it smaller, but the soft solder might mean it wears to a larger size over time. Peugeot 205 Manual . To compensate for this, an air correction jet is inserted in the fuel delivery circuit after the main jet, which starts to add air to the fuel emulsion as the airflow increases. The air correction jet must be SMALLER to enrichen the mixture. We appreciate your continued support and understanding. $7.99 . Note: Do not soak the choke heating element, pump diaphragm, float, vacuum diaphragm, or any other rubber or plastic parts in carburetor solvent. I'd go for a 130 main. 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. Also if you still can't get a slow idle loose the jet a little on the other side of carb were the bypass screw is. The smaller jets WILL NOT work with the 009 distributor. 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, 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. Single 40/44/45mm carburetor, venturi range 28-32mm, Typical displacement of up to 1900cc. Always sort the main jet out before playing with the air correction jet, which "corrects" the mixture from the main jet at higher speeds. Turn the ignition on (but do not start the engine). PRODUCT INFORMATION: All information provided by Aircooled.Net (via website or email) is for USE AT YOUR OWN RISK. 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). As we learn more, we will include it here. IDLE JET .55 .65 .60 (d) VENTURII 40mm . 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. Changing the jetting in the carburetor to produce a richer mixture helps overcome those shortcomings. 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. Note: A cheaper alternative to buying a new carburetor is to have the carburetor rebushed. Change the main first and do a plug read as above. 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. Hey, use the stock jet size, which is 125 for the 34 PICT-3. SUPER-STOCK-34-3. Aircooled.Net has them, and I think Gene Berg in the US has them too. Main jet sizes run through a range from X110 to X150 (1.1 - 1.5mm diameter). 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. Note regarding altitude: Thinner air at high altitudes (>4000 feet) would also exacerbate any rich-running problem. The stock carb has a 26mm venturi. 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. The Pilot Jet Valve (idle jet) would be the g55. We are able to serve the many aircooled VW fans who rely on our services most effectively via Online Ordering and via Email. Discussion in 'Mech Tech' started by low_light_craig, Jun 9, 2017. low_light_craig. The /4 version was used in California and had additional features to reduce emissions. The
The air correction jet prevents the mixture going over-rich at high rpm (again, smaller numbers means richer for this jet). Aircooled.Net, Inc. is in no way affiliated or associated with Volkswagen AG or Volkswagen ("VW") of America. Some of the replacement carburetors (H30/31 and 30PICT/3 maybe???) 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. You'd think the jet sizes would follow the capacity more closely, but they don't. No blue fumes, so the piston rings are well installed. . Note: It is very important that you install the correct needle seat gasket. This gasket sets the fuel height in the float bowl; erratic behavior may result if the gasket is not correct. They might be available individually or in a set. Solex 30 PICT-3, 34 PICT-3 and 34 PICT-4, remove the air bypass screw. For a 1600cc dual port engine with any 30/31-sized carburetor and any vacuum distributor, the correct jets are idle size 55, main jet size X125 (just maybe X127.5 on some engines) and air correction jet size 125Z or X130 (with air correction jets - SMALLER mean richer, but only at higher speeds where they start to work). So VW chose this configuration. Delivery: Estimated between Mon, 6 Mar and Wed, 15 Mar to 23917. You might want to drop a pilot jet size. If it's working, you'll hear a clicking sound as the relay pulls in. Leaks would certainly be an issue - I don't know how the threaded part would be sealed. 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). 55 idle, 127.5 main. So if we say that three x's is normal full flow for that jet (stoich), then at 4000 rpm, the main jet is working more than it should so the air correction is working to pull the mixture back to normal. 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. See our Accelerator Cable Adjustment Procedure. It only works at full throttle and high RPMs ? The optimal stiochiometric (balanced) ratio is 14.5:1 -- that is, 14.5 parts air to one part fuel. There are a few fuels which have up to 85% ethanol in them (E85). If the color of the deposit is tan or brown, you are running too lean and the main jet size should be increased. The selection of main gas and air correction jets is determined by venturi size. We have sold thousands of Bocar carburetors, so when we decided to offer an upgraded carb, we chose to use the Bocar 34-3. 737-240. The adjustable jet would work with any of the Solex carburetors which have the jet mounted horizontally inside the carburetor. This little ball bearing MUST be in place. "N" on the schematic is the coil. "Lean" means less fuel with the same amount of air, and of course "rich" is the opposite. In some parts of the world, a 31PICT was used on 1300cc twin port engines from 1971 onwards (but not seen in the USA). Note: Compressed air is really best if you have it. 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. 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). Here's the story: '68 bug with a ~'73 engine, 1600 dp, dual vac dizzy. 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. the size 65 power jet should work fine for those conditions. SOLEX 34 PICT 3 Carburetor Adjustment Procedures. Main jet plug seal (15)
The air corrections I have are 125z, 170z and in the carburetor a 135z. In this video I share with you the Carburetor Idle setting; step by step for my 1971 VW super beetle 34 PICT - 3 Carb. Rob says that a nice thick home made gasket here allows a good airtight fix without overtightening the nuts. All products purchased should be inspected, measured, cleaned and properly assembled prior to installation. The most common power jet size on all Solex carburettor versions is 65 (except for the H30/31 which usually has a smaller power jet - around 47.5). **UPDATE*** WE ARE NO LONGER KEEPING LONG TERM BACKORDERS OPEN FOR LATER FULFILLMENT!! The H30/31 is the largest carburetor you can use with the normal single-port manifold. Some of you may be using this Carburetor. E10 usually needs a larger main jet and might also need a larger idle jet. Nomenclature
DP case, 1641 P & C, w/ Scat C25 Cam, & stock heads. 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. This helped a lot. SKU: 43-5050-7. To summarize: idle jets operate from idle to 2500-3000rpms or so. 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). This jet is critical to engine flexibility and economy. See our Carburetor Overhaul Procedure. This carb is designed to remain compatible with SVDA distributors, and fits the stock air filter. As a result, we have had to change our BACKORDER FULFILLMENT PROCEDURES. 34 PICT Carburetor Combination, Automatic Choke Discussion and Adjustment Procedure. It would be interesting to try using one an adjustable main jet, but there are some dangers too ? Dave has done so with good success. There should be a light smooth coating of carbon on the rim of the threaded part, and a colour change on the outer electrode of grey (at the tip) to black (where it attaches to the rim of the threaded part), with the change of colour on the corner of the bend. Super Stock 34 PICT 3 (34-3) Carburetor, LIMITED PRODUCTION, 12V, Bocar. So if you get a "too small" jet it's easy to drill out with the right sized drill, but if you get a "too large" jet it's not so easy. Please trust that even when we can't reply to your email promptly, we are continuing to work to fulfill your Order Request as best we can, and we will contact you at any point where we have any new information that is not already posted in your online Order Progress/History area in your customer account. We did a run of these, but due to a limited supply of the quality Bocar 34-3 carbs, we do not know how long we'll have these carburetors! Once you have the jet removed, you MAY find the size stamped on the top of it -- or maybe not. 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. Every engine is different, so strongly consider getting our micro sized idle jets to really dial it in. The 1200cc engines usually used a X120 or X122.5 in the 28PICT carburetors, the 1300cc engines used either X122.5 or X125 in the 30PICT carburetors, the 1500cc engines usually used a X125, and the 1600cc engines usually need a X127.5 in either 30PICT, H30/31, or 34PICT, but MIGHT get away with an X125 in the smaller 30PICT and the H30/31. 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). I have lowered the fuel pressure down to 2.5 psi and checked the float bowl fuel height. If I can't iron it out with the high speed jet I'll start on the idle jet. 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. 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 carburetor has a 55 idle, X125 main and 125 air correction jet. And we will continue responding to emails through until early March 2023 because we are wholly committed to resolving any other issues that may arise from previous sales. (You must log in or sign up to reply here. The 30 and H30/31 carburetors were designed primarily for the 1300-1600cc single port engines, but you can get slightly better performance with the larger carburetors on a 1200cc engine, but only if they are set to run properly with the smaller engine. Following that is a listing of the parts, giving
I tested the operation of the vacuum advance / retard functions of the distributor by sucking on the hoses with the engine running and timing light on . In most cases you can just leave the power jet alone. E85 - forget it for the aircooled VW engine! 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. Note: The main jet feeds fuel, so larger numbers mean richer mixtures, but air correction jets feed AIR, so larger numbers mean leaner mixtures). Located in: Braunschweig, Germany. following diagram. 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. Free shipping for many products! Also check that the valve hasn't worked loose in the carburetor -- they do sometimes, and then work only intermittently. Email care allows us to provide important service detail that can be later referenced by both the customer and our care staff. 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). I've rebuilt the carburettor, and it did not help. 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. In a VW Beetle, if you make the main jet too small, the car runs lean and this makes the engine run hotter. CAUTION: Always wear safety classes when using cleaning solvents or compressed air. 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 effect is clearly noticeable from 3000 RPM upwards (just under 60 mph), and probably a little lower than that. if you look around to really get it right on! Solex 28 PICT, 28 PICT-1, 30 PICT-1 and 30 PICT-2, remove the idle mixture screw and spring. It appears to replace the plug in the bottom of the 30 PICT/1 carburetor float bowl, which has the jet mounted inside and in line with that hole. Immediate shipment of requested products is NOT guaranteed. They are cheap enough. Re: 34 PICT 3 Adjustment Woes. Most gasoline in the USA now has at least 10% Ethanol added (E10), and in other countries, SOME fuel grades have 10% ethanol added. 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 . 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.
