hey guys i am new to the blasters i had it out for a ride and it stalled on me. it is all stock and now as far as i can tell it has spark. i loosen the screw on the carb float and fuel runs out so fuel is getting to the carb. but when i remove the plug it looks dry so i assume no fuel is getting to the engine. any ideas. i am not sure how these engines work so any help would be great. thanks.
