Initial Acceleration Problem

I've got a 74 CJ5, with a Carter YF carb, manual choke and electronic distributor.

Problem is hesitation when I initially accelerate in idle, 1st & 2nd gear. When the engine heats up well, the problem mostly disappears. I've rebuilt the carb, have the idle mixture set more or less correctly for my altitude (6,000 feet) and have sealed all vacuum leaks; though I could probably use a new exhaust gasket, and perhaps that would solve the problem.

But, oddly enough when I have it running, and I manually give it gas...there's no hesititation. But, if I get in and hit the gas pedal...there it is. I've replaced the gas pedal to throttle linkage...so it's not that. And, if I close the choke, let's say 1/8..then there's no hesitation when I apply the gas pedal.

This is not a terrible problem as this baby can really run out. I live in the mountains and even going up a semi-steep grade i'm going 60 with plenty of pedal left.

Anyhow, any hints or insights would be appreciated.
