I have a weber 34/34 and i am after some info on them i have searched the side bar, google and wiki but cannot find anything. i am after some diagrams and some info on the emmision gear.

Any help would be appriciated.

Arent they off an XE Falcon ? Just a thought might be able to find a manual with info that way.

yes they are and i have had a bit more of a look around and found some more info but do you know were i can get a Idle solenoid?

Try Repco or any spares shop.

You just block the the emission bits by tapping a bolt into them or block of with aircraft putty which is much easier.
They flow supposedly a little better than 32/36 as they are built similar to the larger 36/36 with a power valve from what I heard which you can do for the 32/36 but needs a fair bit of stuffing around.

The 36/36 is simultaneous-opening throttles. 32/36 has a power valve, doesn't it?

Yes, 34/34 is not commonly used as a replacement carb, so look for instructions for the specific car it came from.
