F250 Restorer:
Thanks Cliff--

Choke question: I set it cold and the fast idle engages, but it dies several times b/f it will idle.  I have to let it warm up to 180* or when I give it gas it dies. Some times it pops thru carb. Ideas?

Cliff Ruggles:
The pull-off is not correctly adjusted. 

It usually takes a few starts on a dead cold engine to dial them in.  When set correctly, it will fire right up on the fast idle and not die out.

The choke flap is opening too far if it dies out and spits up thru the carb (lean).  Fast idle speed on the high step of the cam could be to slow as well......Cliff
