Why Husqvarna Lawn Mower will not start?
- J
  Julia TaylorJul 29, 2025
  Your Husqvarna Lawn Mower might not start due to several reasons: it could be out of fuel, so refill the fuel tank. The engine may not be choked properly, refer to the “TO START ENGINE” section in the Operation section. The engine could be 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 and refill with fresh gasoline, replacing the fuel filter), loose or damaged wiring (check all wiring). In some cases, the carburetor might be out of adjustment (see “To Adjust Carburetor” in the Service Adjustments section), or the engine valves need adjustment, in which case you should contact an authorized service center/department.

  If your Husqvarna Lawn Mower engine won't turn over, make sure the brake pedal is depressed. Also, check that the attachment clutch is disengaged. Other possible causes include a weak or dead battery (recharge or replace it), a blown fuse (replace it), or corroded battery terminals (clean them). Inspect for loose or damaged wiring. If these steps don't resolve the issue, the ignition switch, solenoid, or starter may be faulty and need checking or replacement. In the case of faulty operator presence switch(es), contact an authorized service center/department.
