Weber IDF Series Air Bleeds
Whats goin on everyone?
I am exited and a bit nervous. My father is letting me work on his 1964 Porsche 356 SC Cabriolet. Whooo hooo! anyways...
My question is, when you are tuning the idle circuit, what symptoms conotate, or in plain english, when do I have to adjust the idle "air bleed"? The Webers (IDF series, I am pretty sure its model 44) have a mixture and idle speed screws (of which I am familiar) but I have not dealt with an "idle air bleed" before. Do you use it when you want to super fine tune the idle after the mixture has been set? I know its used to let air bleed in so the engine will idle smoothly but how do I know if the devil is misadjusted ?
Thanks in advance,

Sorry, but my experience is with Weber IDA's.
The guy you want to talk to is Art Threan, the owner of A.C.E. Air Cooled Engeering in Salt Lake City, UT. Check for his website for more contact information. He is the "undisputed guru" for Weber carbs on all "air cooled" engines. He stocks Weber parts and does complete quality rebuilds. Tell him, you were referred by The Palmer's and saw him run his green and white VW on the Clay Millican Speed TV show "Till it Blows".
"Air bleed's" are to allow the throttle plates to close further, past the idle progression holes in the throttle bores, yet still allow enough air into the carb to idle.Last edited by John Palmer; 04-15-2008 at 10:26 PM.
