  If your Husqvarna Lawn Mower won't start, several factors could be at play. It might be out of fuel, so start by filling the fuel tank. Ensure the engine is choked properly, referring to the “TO START ENGINE” section in the Operation section. If the engine is flooded, wait a few minutes before trying again. Other potential issues include a bad spark plug (replace it), a dirty air filter (clean or replace it), a dirty fuel filter (replace it), or water in the fuel (empty the fuel tank and carburetor, refill with fresh gasoline, and replace the fuel filter).
