Stumped and Frustrated with a Holley 670 Hesitation

Hey Ramie, Maybe I could stop by sometime this weekend and we can swap out my 750 onto your car just to try it. Wouldn't want to mess with any settings because I feel I have it dialed in for my car pretty well finally but I'd be happy to let ya try it at least.

Doug, awesome gesture. If this guy with the carb doesn't have it ready Friday I'll call you. Thanks buddy
