  If your Husqvarna Lawn Mower is hard to start, begin by checking the air filter and replace or clean it if it's dirty. Replace the spark plug if it is bad. If your lawn mower has a battery, recharge or replace it if it's weak or dead. Replace the fuel filter if it's dirty. If the fuel is stale or dirty, empty the fuel tank and refill it with fresh, clean gasoline. Check all wiring for any looseness or damage.
