Re: Rough start
Alan may be on to something. What type of carb does it have? The choke is a very important part of the car starting, warming up and idling cold. If it's out of whack, it will do just what you described. Most every choke, when it is set, should leave about a 3/16" gap between the choke housing and the choke flap. Anything more and it will lean out. Anything less and it will flood. 3/16" is not set in stone, but that is the starting point. Also, when the choke sets, the fast idle cam should be controlling the idle, NOT the normal idle screw. The fast idle cam usually has 2 or 3 steps to it. If you have to keep you foot on the pedal to make the RPM's stay up, then the choke it either maladjusted or the fast idle screw is not set right. Just like the normal idle speed screw, the fast idle cam also has its own idle speed screw that ONLY works when the choke is set. You are shooting for around 1500rpm when the choke is set. I run mine a little lower just because the car is loud and I don't want to wake the neighbors in the morning.
