Many years ago I had a Holley 3 barrel, wow does that age me or what, that thing never ran right. I rebuilt and replaced major parts on it and never solved the problems, the venturi body and throttle section finally ended up in the recycle barrel. The metering plates and float bowls went on to live in other Holley's.
thats what im thinking. I have tried everything thats was in my books and that has been suggested to me. Im have been thinking it is in the manufacturing. What would be a good carb Im thinking that it might be too big for my application. holley suggested at 670 street avenger.
