  Cory VanceAug 20, 2025
  Your Husqvarna Lawn Mower might not start due to several reasons: the fuel tank may be empty (fill it with fuel); the engine might not be choked properly (consult the “TO START ENGINE” section in the Operation section); the engine could be flooded (wait a few minutes before trying again); the spark plug might be bad (replace it); the air filter or fuel filter might be dirty (clean or replace them); there might be water in the fuel (empty the fuel tank and carburetor, refill with fresh gasoline, and replace the fuel filter); there could be loose or damaged wiring (check all wiring). In some cases, the carburetor or engine valves may be out of adjustment, requiring professional service.
