  If your Husqvarna Lawn Mower is hard to start, consider these possible causes: a dirty air filter (clean or replace it), a bad spark plug (replace it), or a weak or dead battery (recharge or replace it). Also, check for a dirty fuel filter (replace it) or stale or dirty fuel (empty the fuel tank and refill with fresh, clean gas). Loose or damaged wiring can also be a culprit, so check all wiring. If the carburetor is out of adjustment, see “To Adjust Carburetor” in Service Adjustments section. For engine valves out of adjustment, contact an authorized service center/department.
