My carb is leaking gas out of the overflow tube when the engine is not running. I took the carb apart cleaned everything and adjusted the floats but it still leaks. Been awhile since I rebuilt one of these carbs but I seem to remember the needle valve having a rubber coating on the end that fits into the valve seat. There's no rubber coating on this needle valve so I'm thinking the it's not seating correctly and stopping the gas flow. Question is should the needle valve have a rubber coating on the end or not.
