I am planning on fully rebuilding a Briggs and Stratton carburetor and i already own a can of Gumout Carb & Choke Cleaner. But on the can it says not to spray directly into the carburetor throat or directly below the throttle plate when the engine is not running. Is it still safe when the engine is off for cleaning the carb with this Gumout cleaner? Also, is there a reason why i can't spray this Carb and choke cleaner into the carburetor throat or below the throttle plate?
