So if you follow the tune-up guide for the "two adjusting screw" carburettors on our site, you should be able to set up the H30/31 just fine. In photo #1, below, this identification is abundantly clear. Your source for ’67 Beetle restoration tips, classifieds, and Beetle stories from around the globe. Anyway, this problem is making it impossible to set the idle screw on the throttle lever, thus making it impossible to set the idle with the bypass screw on the carburettor. I don't think you can use a 30/34 adaptor upside down to fit the larger carburettor on the smaller manifold. The Accelerator Lever now came with an appurtenance where one end of a strong coil spring could be attached. JBugs.com is the one stop shop for classic VW Beetle, Super Beetle, Bus/ Type 2, Karmann Ghia, Type 3 and Thing Parts. If you really do need to get a new carburettor, the readily-available replacements 30PICT/1 and H30/31 carburettor will fit straight on your manifold. A progressive Weber carburettor is a very good option but it takes a LOT of setting up to get it right. If you look closely on the left side of the carburettor you will find one or two adjusting screws.
A stock VW carburetor is proportionally small in relation to VW engine size when compared to most (if not all) other car makes. The Carburettor - General Description and Discussion, Adjustment of "Single-Screw" Carburettors, Adjustment of "Double-Screw" Carburettors, Miscellaneous Topics Related to Carburettor Tuning, 28 PICT-1 & -2; 30 PICT/1 Carburettor Overhaul, Alternator/Accelerator Pump Linkage
These allow better breathing at higher revs for the racers to enjoy, but usually to the detriment of smooth running at low speeds (the engine gets "lumpy" at low rpms). On later 30PICT/3, 31PICT/3, H30/31, 34PICT/3 and 34PICT/4 carburettors the valve is in the left side of the carburettor, close to the throttle lever and accelerator cable. 1. Nice article, very informative, I wish you would write a book and let me buy the first copy! Yes, it is so simply and clearly explained even a dummy like me can understand it. SKP® Carburetor 0 # 3346774643 Volkswagen Beetle 1967, Carburetor by SKP®. jay. You’ve the gift of clarity. The drilling in the Bowl’s bottom takes full advantage of raw gasoline. The VW 105-1 Air Correction Jet would be 125z. Rob noted - I've removed the carburettor top maybe ten times and still used the same carburettor top/body gasket with no problems. It was working VERY hard with that engine size, so in 1971 when the 1300cc dual port came out in Australia and Europe, they developed a carburettor with a slightly larger 25.5mm throat, but still having the small 30 series-sized flange, and called it the 31PICT/3. This site uses Akismet to reduce spam. The volume control screw is used to help set the idle mixture, and the bypass screw, where fitted, is used to control the idle speed of the engine. Automatic Choke
We serve the VW parts and VW Tech needs of owners of aircooled Type 1 VW Beetle, Karmann Ghia, Type 181 Thing, Type 2 Volkswagen Bus, Type 3 VW Squareback / Fastback / Squareback, and Type 411 & 412 Volkswagens. Broad choice of inter-related parts for VW Bugs extends to carburettors, carb return springs, inlet manifolds, fuel pumps, pressure regulators, barbed fuel fittings, air cleaners, Weber carbs, choke elements, needle valves and carburettor rebuild kits… Nothing looks quite like a Beetle, and nothing runs like one either. each part has its own series of numbers 113. In the analysis, the question can be asked: “Does it really matter which Carburetor a person installs onto the Engine of his 1967 Beetle?”, The answer always will be—“For originality’s sake—yes.”. Accelerator Pump
Inside the heads are the Intake and Exhaust Valves. Engine; if it continues as a single pipe from head to head,
Alternator/Accelerator Pump Linkage
Rob responded - As a start, try removing the cable from the throttle arm, and working the throttle arm by hand (holding the stepped cam clear). 34 Series Carburettors
The 30 Pict-1 had been used on the ’66 Beetle Deluxe Model, as well—but, important changes were made for 1967. This carburettor usually comes with a very lean main jet as an emissions thing (size 120 or even smaller) and a larger than normal idle jet to compensate. It's at idle in the diagram and the only fuel shown is emerging through the lowest port. Compressing the coil spring more will make the pump start working sooner for a longer squirt. 101.211 pedestal stand, 113.101.3718, vw (encircled) 28 on the crankcase, 113,101.371B vw 48, on one of the heads. Jay, Product Remark: Works with Air-cooled VW Type 1 with Dual Port manifold. -ES. A view of the side of the VW 105-1 30 Pict-1 Carburetor reveals the casting for the Power Fuel Supply drillings. That's why those who race their VWs are always talking about dual 40mm Kadrons, progressive Webers etc. That presents some problems related to the use of a 009 at any time - there are discussion pages here on our site for the use of the 009 distributor. I’m going to the garage to check for that VW105-1 imprint. Buy a 1969 Volkswagen Beetle Carburetor at discount prices. On a 1600cc the main jet should be a size 127.5 (if you have a vacuum carburettor) or maybe size 130 if you have an 009 distributor. Fast Idle screw which works with the stepped cam to set the idle speed with the choke on. I’m a happy camper! The carburetor is a Solex single barrel model. Float Needle Valve
You can't buy a brand new 30PICT/2 carburettor any more, but you can buy a brand new 30OICT/1, or H30/31 model, which are the replacement carburettors for all the 28 and 30 series. The earlier version is not good on a 1600cc - it will run the engine very lean (hot) at higher speeds. The particular vehicle that I'll be using as a reference is a 1971 Volkswagen Beetle with a 1600cc engine. 12 Volt Choke. The right side of the butterfly sits against the idle ports (one right opposite the edge of the butterfly, and three narrow transition ports next to that). Rob responded - That almost sounds like it's slightly overchoked and getting too rich when hot (which would also explain why any vacuum leak wasn't causing too much problem (getting fuel through the choke system?). 30 Series Carburettors
The larger throated 34PICT series allows better (less restrictive) breathing at high revs, so the engine can develop more total horsepower. Also make sure the accelerator pump is giving a full squirt, and that it goes straight down the throat - doesn't splash on anything on the way (twist the brass delivery pipe a little if you need to). So the 34 copes with this by using 3 fuel circuits - idle, low speed and main. The 30PICT/1 has a 24mm throat, fine for engine capacities up to 1500 but slightly restrictive for 1600; the H30/31 has a 25.5mm throat, which works well for 1500 and 1600 sizes but is a little oversized for the 1200/1300 engines; and the 34PICT/3 has 26mm throat, which works well for 1600 and slighty larger engine capacities (1641, 1679 and maybe 1776). Carburetor Repair Kit. Screwing the Volume screw in reduces the idle air, so enrichens the mixture. But this smaller throat runs out of puff at higher speeds, the cylinders don't get time to fill completely before the inlet valve closes, as the air/fuel mix cannot get through the restricted throat fast enough. Or, if working by myself, I find that I can come very close by adjusting the cable as follows: With the idle screw against the very bottom of the stepped cam, pull the cable back finger-tight and snug down the screw to secure the cable. VW Weber Carb Kit - Beetle (&Super), Dune Buggy, Trike, Type 1 Dual 34 ICT Webers (Fits: Volkswagen Beetle) Genuine Spanish Made Weber ICT Carburetors included. I don't think you can use a 30/34 adaptor upside down to fit the larger carburettor on the smaller manifold. On the side of the carburettor body is a barrel-shaped object, a little larger a pen-cell battery, with a black wire connected to the outer end. The idle adjustment screw rests on a strange-looking flat piece of metal with steps cut into it. on the top of the carburettor bowl. jay. Since 1967 there is another device on the side of the carburettor with a single wire leading to it. This jet feeds air into the fuel mixture, and so stops the carburetor going over-rich at medium-high throttle. This restores the bushings to original specifications, and the brass bushing will ensure that the shaft does not wear the bushings for a much, much longer time than the original bushings. Stepped cam which holds a fast idle when the choke is operating. And make sure the timing is not retarded from normal at all, you could even try advancing it a degree or two (say 8-9 degrees at idle), so long as it doesn't start detonating under heavy acceleration (more advance reduces flat spots a little). See Photo #9 to view the drilling downwards which intersects with the angled drilling. 34 Pict 3. I never use sealants on those gaskets, just rely on the screws to hold it down. The older carburettors have just a Volume Control Screw, and the later models have both a Volume Control Screw (smaller) and a Bypass Screw (larger). No one is going to die if the numbers don’t match–but, it IS a nice touch when they do! Let’s look at some of these changes and why they are important for the 1967 Deluxe Beetle. Great article, JK, and something I recieve emails about weekly. Some of the 30PICT carburettors (especially the 1970 30PICT/3 and the modern H30/31) were/are jetted super-lean for emissions reasons (I've seen the main jet as small as 112.5). 7 product ratings. Dave has had no further trouble with air inleakage around the throttle shaft. The Power Fuel System for the Deluxe ’67 Beetle uses no Check Ball and has a Jet opening of 0.50. Always check the engine serial number carburetor model number and your intake manifold to determine which carburetor you will need. Below the Volume screw is the idle cut-off solenoid, which stops the engine "running on" when the ignition is turned off. VOLKSWAGEN > 1963 > BEETLE > 1.2L H4 > Fuel & Air > Carburetor. Your VW Beetle carburetor blends the right amounts of fuel and air and delivers it to the engine. It’s there! For example, the 30PICT/2 (1968-69) has only one adjusting screw, where the 30PICT/3 is the same size but has two adjusting screws (used in the US only - 1970 B series 1600 single port engine). twin-port (dual-port) heads have two holes in the cylinder head,
You get good mileage when tooling about town, but floor it and the small engines got good performance by using high revs and that second throat. The Pierburg 34PICT/3 Carburettor, Adjustment of "Single-Screw" Carburettors
Carburetor Return Spring. Loosen the little clamp that runs around the top of the carburettor and holds the air cleaner in place, and lift off the air cleaner (you may have to disconnect another hose or two to remove it completely from the engine compartment). For those of us who have not been fortunate enough to have a VW 105-1 Carb already on our Beetle, Eric Shoemaker is scouring the countryside to find suitable 105s for rebuilding. So, if the first three digits of your chassis number is 118, then it would mean that it's a 1968 Beetle. Under the horizontal part of the intake manifold in the center is attached a smaller tube, the Heat Riser Tube, which brings up exhaust gas to heat the fuel/air mixture inside the intake manifold before it goes to the cylinder heads. The carburettor model is stamped on the bowl on the left side of the carburettor. ... Volkswagen Engine Identification. Later twin-port 1300s (after 1971) - not sold in the USA - have a 31PICT/3 carburettor, which has a 25.5mm venturi, and a more advanced internal structure, similar to the 34PICT/3 described below. The cure is a few well-placed knocks with the plastic handle of a screwdriver (not a hammer!) Oh, wonderful, Don! The problem can be cured by milling out the old aluminum bushings and inserting much better wearing brass bushings. VW engines are notoriously under carbureted by nature of the original design. Volkswagen Beetle 1969, Carburetor by DuraGo®. For extra power when needed. Carburetors were stamped by the manufacturer to designate their intended application. Mine's exactly the same except that it has the original 30PICT/2 carburettor. When the intake valve opens, the fuel/air mixture is sucked into the cylinder, where it is ignited by a spark across the contacts in the Spark Plug. Rob wrote ? Carburetor Return Spring. The air correction jet size is very important when using a smaller carburetor on a larger engine. The air correction jet should be about size 125. At the bottom of the carburettor is a second butterfly valve, the Throttle Valve (you can't see it, but trust me) which opens to supply air and fuel to the intake manifold and on to the engine. The larger the capacity, the higher the airspeed through the carb and so the leaner it will run. In photo #1, below, this identification is abundantly clear. Intake Manifold
Since air and fuel do not flow the same, the metering of fuel is NOT LINEAR. Volume screw which adjusts the idle mixture. Brosol H30/31 The Brosol H30/31 is a direct replacement for the 28PCI, 28PICT and 28PICT/1 OEM (original equipment manufacturer) carburetors that Volkswagon's 36- and 40-hp,1,200-cc (cubic centimeter) engines used from 1951 to 1965. is bolted to the top of the Intake Manifold, a metal tube
For emissions and power, the engine has to have a certain amount of vaporized fuel (liquid fuel doesn't burn) for a certain amount of air (often referred to as the "fuel/air mixture"). $64.00. Thank you for being a loyal Reader! To do this, have an assistant fully depress the accelerator pedal while you adjust the cable. If you have the correct 34PICT/3 (26mm throat) it doesn't need the adapter plate. Miscellaneous Topics Related to Carburettor Tuning, Carburetor Overhaul
jay. Any comment? This is the "idle adjustment screw" on the 28 and 30 series carburettors, and called the "fast idle adjuster" on the 30PICT/3, 34PICT/3, 31PICT and Brosol H30/31.
Have you checked and gapped the plugs lately? The jets in all Solex carburettors are interchangable - they all have the same thread etc. This is always open (it's called a "constant venturi" carburettor), so there is a huge variation in the amount of vacuum at the venturi, depending on how open the butterfly is, and of course the engine speed. Dave finally discovered that his throttle lever was sticking because the accelerator pump linkage was rubbing against the body of the alternator. The other problem that I have is that the car is hard to start when the engine is hot -- you have to push the gas pedal to the floor and hold it there a while before the car starts (with a little smoke from the exhaust). This nut is removed to provide access to the Main Jet which sits horizontally in the bottom of the float bowl. 1 product rating - CARB Carburetor Fit For VW/VOLKSWAGEN BEETLE GHIA TRANSPORTER 34PICT carb. Just the hole size is different. Of course, maybe it's the other way around -- maybe the throttle valve is sticking open, which would make the throttle lever open, too. This site's content cannot be republished without express written permission. This valve shuts off the flow of fuel when you turn off the engine, to prevent "running on." The H30/31 also tolerates the 009 distributor better than the 34 sized carburettor -- less likelihood of flat spots. Carburetor Repair Kit. This assures that the engine has a high idle speed when cold (or it would stall), but the idle speed reduces to normal as the engine warm up. Adjustment of "Double-Screw" Carburettors
This is the Fuel Pump. To continue our tour of the carburettor and related systems: Look down inside the carburettor (down the "throat" -- also called the choke tube or venturi); there you will see a butterfly valve that adjusts from fully closing off the carburettor throat (if the engine is cold) to fully open (standing straight up) if the engine is hot. These carbs have a 22.5mm throat. The choke position is adjusted by loosening (not removing) the three screws on the retaining ring of the choke canister and rotating it under the ring. Take a look into the interior of the Fuel Bowl and a hole can be seen to the above described drillings. Thanks for explaining SO clearly. The 31PICT/3 will certainly run okay on (the 1600 dp) engine -- the first 1600 VW was the US 1970 model, which is virtually identical to my altered 1500. This is why it is important not to switch parts from one Carburetor to another unless it can be verified that the parts are for the same model of Carburetor. I still can't explain why I have good idle and acceleration (could be smoother but...) when the volume screw does not work the way it should. The development of the 30/31 carburettors is interesting... the 30PICT series has a 24mm throat, and it's final development was the 30PICT/3 used in the 1970 1600 single-port engine (in the USA). The last six to seven digits are the chassis serial number. Adjusting the carburetor on your old beetle isn't as hard as it may sound. Brosol H30/31 Carburettors
© Lane Russell LLC - 1967beetle.com. The Power Fuel System had been used on some previous Carburetors, but discontinued until the advent of the 1967 Model. Welch Plugs, Carburettor Interchangeability
you say the car is running well (except for maybe a slight choke adjustment), and your fuel economy is about right for that engine/carburettor combination In US gallons, 25-28 mpg for the single-port 1500/1600cc engine with 30PICT/2 carburettor. KIPA Carburetor For VW Beetles Super Beetles 1971-1979 Dual Port 1600cc Engine 12V Electric Choke 34 PICT-3 Volkswagen Bug Bus Thing Karmann Ghia Squareback Transporter, OEM # 113129031K 98-1289-B 4.4 out of 5 stars 45 the carburettor down to the sides of the engine, where it attaches
These carburettors have a 22.5mm throat. On the bottom of the carburettor bowl on the left side is a large nut. LOL Besides, it is fun to know how these things work. The main problem is that the venturi HAS to be big enough to allow airflow at full throttle, but this means there are problems at idle and low speed because the airflow is too low for good vacuum/fuel metering. 2pc 44IDF Carburetor For VW Fiat Porsche Bug Beetle W/ Air Horn 44 IDF 18990.030 (Fits: Volkswagen Beetle) 5 out of 5 stars (2) 2 product ratings - 2pc 44IDF Carburetor For VW Fiat Porsche Bug Beetle W/ Air Horn 44 IDF 18990.030 There is another connection point on the fuel pump with a metal or rubber line attached to it. The third digit is the last digit of the year, for example 5 would indicate 1965 and 2 would indicate 1972. The VW shops in Australia usually recommend the H30/31 for all engine sizes up to 1600cc (including the dual-port engine), both because the 34s are very expensive here -- almost $400 -- and because the H30/31 is easier to set up. to the Cylinder Heads on either side. 2. Be sure the wire is connected and that it runs to the (+) terminal on the coil. Question - I have a simple question about the Solex 30 PICT/2 carburettor. The casting extends along the driver’s side at an angle from the Bowl, then upward to the the Carburetor’s top half. Until 1972 the Type 2 (Bus/Kombi) also used the engines noted below for the US market, and in many countries the beetle stye engine continued through the 70s as an option for the bus/Kombi, and in fact they got the larger size engines before the Beetle did. The Japanese cars used to use them a lot. (Also attached to this terminal is the black wire that provides power to the automatic choke.) Vapor Lock
How to Set the 34Pict/3 Carburetor on an Aircooled Volkswagen (Vw) Beetle. Note: You can test the operation of the idle cutoff valve solenoid very easily.
Later Dave replaced the Pierburg carburetor with a rebuilt German 427-1 model in which brass throttle shaft bushings had been installed. The 1600cc DP can flow more air than the 1600cc SP and smaller engines. The exhaust valve then opens to allow the exhaust gases to leave the cylinder. Top Rated Seller Top Rated Seller. Throttle Shaft Bushings
So it is often used with a non-vacuum distributor like the 009. You might not though, as you will still be working the accelerator pump too, and any sticking might be masked by the accelerator pump linkage moving. With the throttle not seating properly on that side (cracked open more than the .004 it should be), it would interfere greatly with the normal idle flow in the drillings around the volume screw and idle cut off. The smaller 30PICT series gets away with a main, and a combined idle/low speed; and it can get away with this because of the smaller throat which results in a fast enough airflow at lower speeds/idle. At Engine # F0 429813 and Chassis # 116-460-614 Thank you, David! You might just feel something if you are lucky. So you set the idle speed to 850rpm or so, then use the volume screw to get the fastest idle, then reset the idle speed using the throttle arm screw. 34 PICT/3 Carburettor Overhaul, Related Topics
All of these smaller carbs must be jetted to suit the larger engine (I can recommend ball-park jet sizes) and they sit on the twin port manifold with a 30/34 adapter plate. And since higher airfow means a higher vacuum in the throat, this sucks in more fuel for a richer mixture, so you then have to enlarge the air correction jet to match the higher airflow. Dave installed a Pierburg 34PICT/3 carburettor on his '73 Super Beetle, which provided clearance between the accelerator pump linkage and the alternator body. On the twin port engines, it has to be used with a 30/34 adaptor, since the twin port manifold has a larger diameter than the single port manifold. The idle jet should be a size 55, and power jet size 65. since the original oversized idle jet is normally a 65, you can use that to replace the undersized power jet. 34 PICT-3 Stock Replacement Carburetor for the Type 1 and 2 Bug, Bus, Ghia & Thing with Electric 12 volt Choke. Intentionally blank: Intentionally blank: Related Parts. Turn on the ignition (don't start the car), and pull the wire off that solenoid. I also have an extra 34PICT/3 carburettor from an old '74 that I parted out. What this means is that you can have correct metering at some engine speeds but not at others. Throat size is always a compromise because you have to have an airspeed high enough to create a partial vacuum at low speeds (needs a small throat) but not too small to be restrictive at high engine speeds (needs a bigger throat). Throttle Linkage. Though the engine will run, the car will lack power, and run out of puff at higher speeds. But it also has to operate at idle and cruising speeds. Whereas Carburetors previously had employed a tube-and-spring-and spring keeper return mechanism for the Accelerator Lever, Solex engineers developed a simple way to attach a strong Return Spring which dismissed the former clumsy tube-spring-keeper mechanism. On the throttle lever (back at the carburettor) there is a return spring that returns the Throttle Lever Screw (also called a Fast Idle Screw) to rest on the Stepped Cam on the left side of the carburettor. one for each intake valve, since the split occurs in the intake
7 product ratings - VW Weber Carb Kit - Beetle (&Super), Dune Buggy, Trike, Type 1 … Carburetors for other applications (Karmann Ghias, Buses) were stamped appropriately. Could this be fixed by adjusting idling? Intentionally blank: Intentionally blank: Related Parts. Confused? You and Mary take care–hope to talk again soon. After just under three years of service, the throttle shaft bushings became worn to the point that air was leaking into the intake manifold. Stay tuned! It had 1600 cylinders, with single port head and 30PICT/3 carburettor. A 113-905-205T from a 71 or newer Beetle should work with a 30 PICT-3 Carb. Note: Before adjusting the carburettor, it is essential that the accelerator cable be properly adjusted. Everyone loved the new design. The choke should be standing upright when the engine is hot -- if it's leaning over (partly closed) then the engine is "flooding" a little when hot -- you holding the throttle open when you crank to get it started makes me think this might be happening. Price: Core: Total: Alternate: No parts for vehicles in selected markets. Photo #10 reveals the continuance of drilling into the top half of the Carburetor which matches that of the drilling in the bottom half of the Carburetor. These have a 24mm throat. This is the idle fuel cutoff valve (solenoid). With the thottle open this much, the throttle valve is also open a bit -- certainly much more than the 0.004 inch it's supposed to be. Interference
This is the fuel supply line. 1 Piece. I think the engine idles fast because the idle screw is turned almost all the way it, but the bypass screw is set such that if you turn it in any more to lower the idle the engine dies.
