Hello fellow listers:

I have a Weber rebuild kit and it came with twelve "o" rings. The original Webers that I took apart had no "o" rings.

I have been able to find six "o" rings in the Pierce Manifolds exploded view of an IDA Weberthat go on the six Idling mixture adjusting screw, but where do the other six go?

My best thought is the under the pump jet spigots on top of the venturi from the accelerator pump.

Thanks in advance, Tom

The other 6 O-rings are used on the idle jet holders to seal them against the car bodies; that exploded diagram has several things missing,....

Thank you Steve!!

Early Webers did not use o-rings for the idle fuel jet carriers; don't try to use them in that application because they will tear and pieces will get lodged in carb passages - not good! A possibility as to why the kit came with 12 o-rings is that if the kit also services 40 TIN Zeniths (used on 2.2 Ts) the extra 6 o-rings will be for the injection pump nozzles.

That's great advice.
