  If your Greyhound Portable Generator engine suddenly stops, it could be due to several reasons: the engine oil is low, the fuel tank is empty or contains impure or low-quality gasoline, the fuel tank cap is defective and creating a vacuum, or the magneto is faulty. Ensure the engine oil is filled to the proper level and that you check it before every use. Refill the fuel tank with fresh 89+ octane unleaded gasoline. Test or replace the fuel tank cap. If these steps don't resolve the issue, have a qualified technician service the magneto.

  A Greyhound Portable Generator engine can backfire due to impure or low-quality gasoline, the engine being too cold, or a stuck intake valve or overheated engine. Try filling the fuel tank with fresh 89+ octane unleaded gasoline. Use cold weather fuel and oil additives to prevent backfiring. If the issue persists, have a qualified technician diagnose and service the engine.

  There are several potential reasons why your Greyhound Portable Generator might not be starting. It could be fuel-related, such as an empty tank, a closed fuel valve, the choke not being in the start position, old or low-quality gasoline, a carburetor that's not primed, dirty fuel passageways, or a stuck carburetor needle. Alternatively, it could be ignition-related, such as a loose spark plug wire, a dirty or wet spark plug, an incorrect spark plug gap, or a broken spark plug wire. Finally, it could be compression-related, such as a cylinder that's not lubricated, a loose or broken spark plug, a loose cylinder head or damaged head gasket, or misadjusted or stuck engine valves or tappets. Try filling the fuel tank and opening the fuel valve. If the engine is cold, move the choke to the sta...
