Have a problem with the two Holley Model 4000 Carburator with Integral Choke (Tee Pot Carburator) Both have a new Overhaul Kit from Daytona Parts Co. installed. The Problem I'm facing is: Idle Speed is oscillating (pumping) within about 1 – 2 sec. period. Has anybody an idea where to start playing around adjusting things?

Experts on vintage Holley Carbs are not easy to found in Switzerland! Many thanks for valid hints. Regards Rene
