Re: Holley Carb Help

I read that with my current vacuum reading in drive that the stock power valve is ok.

Not sure about a possible restriction in the fuel line. Runs great at WOT, just hesitates right at the transition point.

I'm thinking about playing with the timing and or changing the squirter size a few sizes up. Hopefully one or both of those things will help.
