  Heidi DunnAug 21, 2025
  If your Husqvarna Lawn Mower won't start, several factors could be the cause. First, check if the fuel tank is empty and fill it if necessary. If the engine isn't choked properly, refer to the 'TO START ENGINE' section in the Operation section. If the engine is flooded, wait a few minutes before trying again. Other potential issues include a bad spark plug (replace it), a dirty air filter (clean or replace it), a dirty fuel filter (replace it), or water in the fuel (empty the tank and carburetor, refill with fresh gasoline, and replace the fuel filter). Also, check for loose or damaged wiring. If none of these steps work, the engine valves may be out of adjustment, and you should contact an authorized service center.
