  There are several reasons why your Husqvarna Lawn Mower might not start. It could be due to: * being out of fuel (fill the fuel tank), * improper choking (refer to the “TO START ENGINE” section in the Operation section), * a flooded engine (wait several minutes before trying again), * 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 fuel tank and carburetor, refill with fresh gasoline, and replace the fuel filter), * loose or damaged wiring (check all wiring). Other potential causes include 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).
