I have a 1963 valiant 170 with a Holley 1920. I had the engine rebuilt and at the same time the carb was also redone. The engine starts and runs great when cold. When the engine warms up, I can barely keep it running. It appears to be a carb issue, but the guy who did the work cannot figure it out. I know that there is a wealth of knowledge here. Can anyone offer some advice?

Yes, that is when it starts running bad is when the choke opens all of the way. It does have a heat riser.

I would also check for vacuum leaks. The choke can cover those up when its closed.
