Default Re: Hot idle adjustment screw

The hot idle speed adjusting screw (with the spring on it) is supposed to contact that round pin directly in front of it. Either the dashpot screw on the throttle lever is adjusted too far out, or the fast idle cam on the other side of carb isn't dropping (choke not all the way opened ?). Or the return spring on the throttle linkage isn't working.
