OUR ONLINE CHECKOUT is CLOSED and we are NOT accepting any NEW orders at this time.

We are still fulfilling and shipping previously submitted and/or delayed order requests (as product availability allows) UNTIL NOVEMBER 15th 2022.

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).

Our ability to respond to emails is greatly hampered by being under-staffed during this downsize transition time. But we continue to endeavor to answer email inquiries as best we can. 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. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023.

We sincerely appreciate your patience, understanding during this period of restructuring and/or closing. And a huge thank you to all of you whose support and loyalty we have been the beneficiary of over the 23 years that we have worked diligently to support the information and parts needs of the aircooled VW community!

ACN Flanged Racing Intake and Exhaust Nut, 8 x 10mm, EACH
ACN Flanged Racing Intake and Exhaust Nut, 8 x 10mm, EACH
Price: $0.95

ACN Flanged Racing Intake and Exhaust Nut, 8 x 10mm, EACH were designed after evaluating all problems with other nuts. We tried to solve them all with this product! 8mm threads, with a 10mm 6pt hex, and a 13mm flanged bottom to spread the clamping forces! You can torque these to 35lb/ft, though we feel that is excessive. The threads fail at just over 40lb/ft. We have tried these in several different alloys (including Stainless Steel) and success with one combination was the one we used!

Once you use these you will never EVER go back to the Brass Nuts (that strip and round off), or the barely better 12mm ones out there.

These are a LOT smaller than 11mm on the Head, and the flange keeps the header far enough away from the nut to allow your socket or wrench head enough room to get on and off!

We use these all over because they are so useful. The obvious application is header nuts, when you have a larger than stock header. These even work on exhausts as big as 2 1/4"!!!!! The not so obvious application are to hold down your intake manifold(s)! Now you have a ton of room to use a FAST Ratchet with a long extension above the carb top! You can take a dual carb system off in under a minute after a little practice! Imagine, no more bloody knuckles after an hour of fighting your car!!!!

Weber IDF Throttle Stop Screw (Idle Speed Screw), 64625.015
Weber IDF Throttle Stop Screw (Idle Speed Screw), 64625.015
Price: $3.95
Item eligible for Econo/1st Class Mail shipment, min ship charge applies

Weber IDF Throttle Stop Screw (Idle Speed Screw), 64625.015 is the screw which sets where the throttle plates are in their CLOSED position. Idle speed adjustments are made by turning this screw in or out, then the idle mixture is set afterward. These are often bent or grooved.

Proper idle settings are achieved by fully warming up the engine, set your ignition timing, then sync the carbs. Next adjust idle mixture, then idle speed, idle mixture, idle speed, and idle mixture. At this point you are likely not changing anything and you are done!

To set idle mixture, turn the idle mixture screw to fastest idle speed. it's best to turn it in too far 1 bbl at a time (bottom it out lightly, idle speed will drop as you lose a cylinder), and as you turn it out the cylinder will come back, picking up idle speed. Set for fastest idle, + 1/2 turn out (richer). The extra 1/2 turn makes for a more STABLE idle (not a better one).

Note that any time you change the idle speed, carb sync, idle jet size, or ignition timing, you must re-set the idle mixture!

Weber IDF Air Bypass Screw, EACH, 64750.029
Price: $7.95
Item eligible for Econo/1st Class Mail shipment, min ship charge applies

Weber IDF Air Bypass Screw, EACH, 64750.029 is a small screw at the carburetor base, which regulates how much air is bypassing the idle circuit. This is used to micro adjust and balance flow at idle and low speeds, between barrels on the same carburetor. On any carburetor, one Air Bypass Screw should be fully closed (seated), and the "Low Flowing" barrel should have the screw turned out slightly so the flow at idle matches. If you have a huge difference between barrels, either the throttle shaft on the carburetor is twisted, the throttle plates are improperly installed, or the engine has a mechanical problem causing low flow (vacuum).

Any tmie you change the idle speed, carb sync, idle jet size, or ignition timing, you must re-set the idle mixture!

Aircooled.Net only carries ORIGINAL Weber JETS FROM ITALY, we do not carry Chinese reproductions which do not flow properly! These are all genuine Weber jets which have been flow tested at the factory. Our jetting guide down below will really help you dial in your carb!

Jets are sized in "milimeters", so a "200" jet is very close to 2.0mm. Actually they are rated on flow not size, after they are measured on a flow machine. That's why drilling and reaming jets is not necessarily a good idea, since drilling or reaming can result in a 180 air flowing more than a 190 air, based on orifice length and entry/exit radius, etc.

7mm Low Pressure Fuel Hose, 7.0 X 2.5mm
7mm Low Pressure Fuel Hose, 7.0 X 2.5mm per meter
Price: $11.00

7mm Low Pressure Fuel Hose, 7.0 X 2.5mm is the best carbureted fuel hose in our opinion. This is braided for abrasion resistance, and has a cloth braid covering, that is easy to grip to put the hose on and off. The covering also looks "new" far longer.

Hose clamps are not even needed, because the cloth woven on the hose surface acts like a "Chinese finger trap", and keeps the hose tight on the fitting. Some owners choose to err on the side of caution and use clamps also.

Price is for a meter of hose.
