enigne stumbles

ive been playing with my car after the rebuild, and when i get on it from a stop it stumbles, falls flat on its face, and then kinda remembers what it was doing and is fine, better than fine. After it makes it outta first gear it flies. anyway, would anyone have a suggestion as to why it would stumble like that?

It could be numerous problems, but we will need a better description... Does it actually bog down?? I sounds to me like a fuel/ignition problem, but very hard to pinpoint with the description you have given us...

It's inside the carb.
To verify ops, remove air cleaner so you can see down the front bores of the carb. Shine a bright light in there. Rapidly open the throttle (this is with eng off) and look for a good squirt of fuel into the bores of the carb.

When the throttle is opened rapidly, the eng sucks in a bunch of air. You need a squirt of fuel to keep the air/fuel mixture correct during this transition.
