They might be available individually or in a set. Ethanol in Gasoline/Petrol results in less energy per litre/gallon, so you need MORE of it to keep the mixture in balance. The effect is not linear though, so as the airspeed increases, the main jet will start to deliver a richer mixture (too much fuel), so the air correction jet is needed to add air and stop the mixture going over-rich, then the air correction jet starts working too well at higher airflows (engine revs) so the Power Jet (Aux jet) is need to add more fuel again. Nomenclature Note: Compressed air is really best if you have it. It's important that you get it right. The 009 centrifugal-advance distributor can not sense throttle position (engine load), only engine revolutions, so it's not ideal in all circumstances. "N" on the schematic is the coil. We need to do some research regarding the adjustable main jet. The Power Fuel System Dispensing Nozzle for the VW 105-1 would be 0.50 with no check ball. For example, when used on a 1300cc engine with a vacuum distributor, the H30/31 should usually have a main jet of X122.5 and an air correction jet of about 140Z; but when used in a 1600cc single port engine, it should have a 125 main jet and a 125 or 130 air correction jet. by vwlover77 Fri May 05, 2017 6:58 pm. Items that are not expected to be restocked within 2 weeks WILL BE AUTOMATICALLY CANCELLED. Main jet plug seal (15) 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. It would be interesting to try using one an adjustable main jet, but there are some dangers too ? 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. Pass the end of the accelerator cable through the cable pivot pin installed in the throttle lever. Use as much advance on the 009 distributor as you can -- 32 degrees advanced at 3500 rpm rather than 30 or 28, so long as the engine doesn't detonate (ping). Idle jet sizes of 70 or so will "run" on anything, but they don't run WELL (unless fouled plugs or 12mpg are your idea of "well"). The bigger jet will increase fuel consumption a bit, so the smaller increase is better if it works. 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. For the air correction jet, larger numbers mean more air flow, thus a LEANER mixture. You can also get detonation (pinging/knocking) if the engine gets too hot. Same with the carburetors in general, so adjustments become essential. mains: 120, 130, 135, 145. air jets: 160, 170, 180, 185. We appreciate your continued support and understanding.

If the color is rich grey, you're about right. 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. Email care allows us to provide important service detail that can be later referenced by both the customer and our care staff. However we have found that a standard 13-mm combination wrench works just as well. 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, or the engine will run rich at medium-high throttle. PRODUCT IMAGES are representative only. So why worry about the jets? Our last contact with Keith was some years ago. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023. Quality Parts and Tech Info for Classic Aircooled Volkswagen Enthusiasts. .

You may have to get creative about how you attach so many wires to the single terminal on the coil. All this indicates a good mixture and correct heat range. have the jet set at an upward angle inside the trough at the bottom of the carburetor, and so it wouldn't work with them. Seller pays for return postage. These are setup for 12V electrics, and include the idle shut off valve. Our 74 Super has a tube running from the 34 PICT 3 down, and is .

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. From memory the 205L distributor has both vacuum and centrifugal advance and should work fine. The fuel screw setting at idle trims the pilot fuel, and considering the fuel screw ends up at 1.5/1.75, the 1/8 throttle position (all 100% pilot flow) will be rich. 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).

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). 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). We ONLY charge for items that are available to be shipped in a timely or reasonably reliable timeframe. $7.99. Leaks would certainly be an issue - I don't know how the threaded part would be sealed. 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.

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. Our ability to respond to emails is greatly hampered by being under-staffed during this downsize transition time. That's fine for modern cars with engine computers which can adjust the mixture on-the-run, but what about our old fixed-jet carburettors? 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. *** 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.

So with a vacuum distributor, using a 55 idle, X130 or X132.5 main and about a 100 - 120Z air correction jet should provide good mixture for a 1776, without affecting fuel economy to badly (fuel consumption WILL be a little higher with the larger capacity though). 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. Brosol/Solex Idle Jets .50.

Lightly lubricate the choke valve shaft and throttle valve shaft with engine oil and the external linkage with molybdenum grease. 2-F7 emulsion tubes for the IDF. Note: You will be removing a number of small parts in this process; hopefully "stow them in a safe place" goes without saying. 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. See details. It's a complex problem that faces ALL open throat style carburettors. PLEASE NOTE: You are NOT CHARGED for out-of-stock items. I'd avoid Chinese stuff on eBay. You must do the opposite -- make the main jet a little bigger (X130 or X132.5) to stop the engine from hesitating when you accelerate. and 34-3 carb.

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. 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.
