Hey Falcon. What plane and engine do you have. If you have a electric starter you could actually put the starter up to the spinner and just let it turn for a few seconds, the fuel will come up on it's own(at least it's that way on my planes). Also you forgot the single most important thing when starting a glow powered engine. The glow plug igniter. Try to fuel the plane up, put the igniter on, and if you are using an electric starter, just try to start it. After a cople seconds the fuel should come up and the engine should start. Also Flyboy is right, it could also be the nedle valve. Good luck, Gary
