Why Husqvarna LB 146 engine does not start?

  Your Husqvarna Lawn Mower engine might fail to start due to several reasons. It could be due to the ignition cable not being correctly connected, which requires you to connect the ignition cable to the spark plug. Another reason could be an empty fuel tank, which requires you to fill the tank with the correct fuel type. Old fuel can also be the culprit, so drain the tank and carburetor and refuel with fresh gasoline. A dirty carburetor or fuel line needs cleaning, while a defective spark plug should be adjusted, cleaned, or replaced. Finally, fuel on the spark plug requires cleaning.

  If your Husqvarna Lawn Mower engine isn't running smoothly, several factors could be responsible. First, check the ignition cable and ensure it's correctly connected to the spark plug. Dirt in the fuel line or old fuel can also cause issues; clean the fuel line and refill with fresh fuel of the correct type. A blocked fuel tank cap should be cleaned. Water or dirt in the fuel system requires you to drain the tank and refill it with new fuel. A dirty air filter should be cleaned. 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 could be due to a low engine oil level; in this case, you should add engine oil. Insufficient airflow can also cause overheating, so clean the air filter and its housing. If these steps don't help, the carburetor may need adjustment by a servicing dealer.

  If your Husqvarna Lawn Mower engine isn't running smoothly at idle speed, the spark plug might be dirty, defective, or have too wide of an electrode gap; adjust the gap or replace the spark plug. Alternatively, the carburetor may need adjustment, or the air filter could be dirty and require cleaning.
