  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.

  If the engine of your Husqvarna Lawn Mower won't turn over, make sure the brake pedal is depressed. Also, ensure the attachment clutch is disengaged. A weak or dead battery can also prevent the engine from turning over, so recharge or replace it. Check for a blown fuse and replace it if necessary. Clean any corroded battery terminals. Inspect all wiring for looseness or damage. If the ignition switch is faulty, check or replace it. Similarly, check or replace the solenoid or starter if they are faulty. For faulty operator presence switch(es), contact an authorized service center.
