Look at the carb baseplate throttle shaft itself. If that wears down (it only runs on bronze bushings usually) then you get air leaks there. I am not going to recommend spraying starter fluid around the baseplate but some people have done that. With an air leak you will get a jump in the idle speed. Just saying, some people have done that before. If you do, be careful!!!!
