You should only adjust the idle stop screw and idle mixture screw. Use a low speed tach and set the idle stop screw (end rests on the throttle linkage lever stop, back side of carb, low) so the fully warmed up curb idle is about 750-800. Then adjust the idle mixture screw (driver's side of the carb, middle, low, angled slightly down) to get the highest idle speed, then readjust the idle speed, then readjust the mixture.
