Hello. My name is Tan.

If the engine runs on alternate fuel source then you have debris in the fuel tank clogging the pick up tube screen, kinked or clogged tank vent, bad anti siphon valve or a collapsed fuel supply line coming from the tank to engine.

Have you done any of these checks? Do you need help with any of these checks?
