Also, hold the carb up to a light and check the throttle butterflies for evenness in the venturies and loosten the screws and get em as even as possible then red locktite and you`re golden.

Normally zero gap unless you`re trying to delay/lean shot.

Normally zero gap unless you`re trying to delay/lean shot. that's actually why I had it loose but I guess there is a limit.but it worked great for awhile.theoretically you should be able to run a gap for a delayed shot.i still don't know why it was acting like that. but it will prob happen again when I somewhere where it will embarass me.

Why would you try to purposely create that situation?(trying to delay/lean shot)

Some I know and study go to great lengths to "fine tune" every inch and that means sometimes slowing down or delaying shot based on fuel curve data.........

I've seen a bunch of stock Holley Dominators as well as other D.P. come from Holley maladjusted like that Another one of the checks you need to perform beofre using any of them

Another trick great for footbrake racers is to use a smaller secondary squirter if it`s too rich when nailed..........I`m messin w/that now on my junk.
