Hesitating Holley

[MotownMadman]

Marlin, I read this whole thread, one thing comes to mind as for an initial stumble, you said it worked fine until you removed, rebuilt and reinstalled. One thing I would check is for a vaccum leak on the base gasket, even the smallest leak coming off idle can cause enough of a unmetered air draw to make the car stumble. Several ways to check for a leak, I am sure you know the protocol on that. Just a thought.
