Why Husqvarna Lawn Mower will not start?

  tina20Jul 30, 2025
  Your Husqvarna Lawn Mower might not start due to several reasons: the fuel tank may be empty, so you should fill it. The engine may not be choked properly, so check the “TO START ENGINE” section in the Operation section. If the engine is flooded, wait a few 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 that is out of adjustment (see “To Adjust Carburetor” in the Service Adjustments section), or engine valves that are out of adjustment.
