  Steven WilsonAug 20, 2025
  Your Husqvarna Lawn Mower might not start due to several reasons: it could be out of fuel, so fill the fuel tank. The engine might not be choked properly, refer to the “TO START ENGINE” section in the Operation section. It's possible the engine is flooded; wait several 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 out of adjustment (see “To Adjust Carburetor” in the Service Adjustments section), or engine valves out of adjustment (contact an authorized service center/department).

Why is the cut quality poor and uneven with my Husqvarna Lawn Mower?
- C
  Corey AdamsAug 30, 2025
  An uneven cut with your Husqvarna Lawn Mower can result from a worn, bent, or loose blade; replace the blade and tighten the blade bolt. It could also be that the mower deck is not level, so level the mower deck. A buildup of grass, leaves, or trash under the mower can also cause this, so clean the underside of the mower housing. Additionally, a bent blade mandrel or clogged mower deck vent holes can be the cause, so replace the blade mandrel or clean around mandrels to open vent holes.
