Hi Ed my name is ***** ***** welcome to Just Answer. It sounds like the needle and inlet valve aren't seating . When that happens the float closes and gas continues to fow which fills up the bowl and bypasses the carb and rus out the carb , it could also run down into the engine , past the valves and mix with the oil in the crankcase. To fix it it would need a new needle and inlet valve
