  If your Husqvarna Lawn Mower engine won't start, several factors could be the cause. Ensure the ignition cable is correctly connected to the spark plug. If the fuel tank is empty, refill it with the correct fuel type. Old fuel can also be a problem; in this case, drain the tank and carburetor and refuel with fresh gasoline. Check for dirt in the carburetor or fuel line, and clean them if necessary. The spark plug itself might be defective, so adjust the electrode gap, clean, or replace it. Finally, if there's fuel on the spark plug, clean it off.

Check the fuel line for dirt and use new fuel of the correct type. Also, ensure the fuel tank cap isn't blocked. If there's water or dirt in the fuel system, drain the tank and refill it with new fuel. Clean a dirty air filter. If these steps don't resolve the issue, a servicing dealer may need to adjust the carburetor.

  If your Husqvarna Lawn Mower engine is overheating, it might be due to a low engine oil level. Make sure to fill the engine with oil. Insufficient airflow can also cause overheating, so clean the air filter and the air filter housing. If the problem persists, the carburetor may need adjustment by a servicing dealer.
