Hello all. Straight to the point: car runs and drives perfectly fine. Starts fine, idles at 1000-1100 in park when warm and 6-700 in gear when warm. Reaches operating temp, oil temp, all the good stuff. The question I have pertains to the idle speed screw on the lower driver's side of the carb. Mine can be backed all the way out, so far as it is not touching anything anymore, and the engine still idles at 1000 rpm. Is this normal? I can back the idle screw off and pull forward on the linkage and make it touch the backed out screw and the idle will go down. Carb works fine otherwise. Any ideas? I have all the linkage I can pilfer from other carbs I have, but I'd rather not take it apart if I don't have too.
