I have a brand new Edelbrock Performer (750 CFM) carburetor, and I was wondering if anybody is familiar with adjusting the “fast idle” for the choke? It is idling too high when the choke is on. I would like to get the fast idle down to about 1000 RPM. I have the Owner’s Manual, which came with the carb, but it only shows which screw to turn, in order to adjust it, but not which way to adjust it. Does anybody know if I am supposed to turn the screw out to lower the Fast Idle RPM’s, or in?
