eric32, I took a look at a thread you had about a carb: Opinion on Holley 670 street avenger pics inside
If this is the same carb you're now using, I have a concern. You mentioned the air bleed bypass in the center of the carb. Said that you were "going to leave it out for now", or words to that effect. Which should have been fine...
But, if you removed the air bypass jet entirely
, that could have
created a vacuum leak- IF the center channel has been opened up already. If
that is the case, the orifice that the air bleed occupies needs to be either blocked off entirely w/an undrilled jet, or have a small diameter hole drilled to provide an air bypass to let a big cam idle w/o opening the primaries too far, ala the BG Idle Eze.
Just because the channel was supposed
to be closed off, I wouldn't take that as gospel. I'd check it to be positive.
