My carburetor number is 17056540, and looking at my notes I have measured the air bleeds as .060 in air horn and .046 in main body, I am using .073 jets with matching metering rods from Cliff's shop. My question is should I enlarge these air bleeds to allow more emulsion air in fuel delivery? In Cliff's excellent book the "recipe's" on pages 111 to 114 list the air bleeds at .070 for both locations. Thanks, Al
Depends on what cam and engine it is going on. I put a pcv on 455 that does not let as much air through it because of cam. it's hard to say.
