The carb is fairly sealed off from the muffler on those but it is possible that the heat could be rising and vapor locking the carb. Fuel coming out of the carb after shut off seems more like a pressure problem forcing fuel through the carb. Primer bulbs that are not sealing and allow fuel flow backwards through them toward the carb will cause the symptom you are discussing.
