Why my Husqvarna Lawn Mower will not start?
- M
  Mrs. Elizabeth Williams MDAug 23, 2025
  Your Husqvarna Lawn Mower might not start due to several reasons: it could be out of fuel, so fill the fuel tank. The engine might not be choked properly, refer to the “TO START ENGINE” section in the Operation section. It's possible the engine is flooded; wait several minutes before trying again. Other potential causes include a bad spark plug (replace it), a dirty air filter (clean or replace it), a dirty fuel filter (replace it), water in the fuel (empty the tank and carburetor, refill with fresh gasoline, and replace the fuel filter), loose or damaged wiring (check all wiring), a carburetor out of adjustment (see “To Adjust Carburetor” in the Service Adjustments section), or engine valves out of adjustment (contact an authorized service center/department).
