I cleaned out the carb on my motorcycle and the varnish from old fuel made the screw fit fairly tight. However after I cleaned it with b-12 carb cleaner the idle screw is so loose the vibration makes it turn counter clockwise freely. Now what can I add to the threads of the screw to make stick better but not dirty up or clog the carburetor.
