Your right I did not realize he was in 170 section i am bad.If it is a fuel issue.We had the same problem happen to my daughters a few times also. Got an air lock in the fuel system. Basicly you just have to fill the tank almost overflowing it. Getting any air out of the tank, remove the fuel line from the carb. keeping it lower than the tank as possible. Tighten the gas cap. Crank the engine until fuel comes. I doubt the fuel pump is bad there is not much to go bad on it.
