If your Husqvarna Lawn Mower engine isn't running smoothly, several factors could be the cause. Start by replacing the spark plug if it's defective. Clean or replace the air filter if it is dirty. Replace the fuel tank cap if the check valve on it is defective. Fill the fuel tank with fuel if it’s almost empty. If there is water in the fuel, remove all fuel from the fuel tank and the carburetor, then fill the fuel tank with new fuel and replace the fuel filter. Disengage the choke if it's engaged and the engine is warm. If the fuel mix or fuel type is incorrect, remove all fuel from the fuel tank and the carburetor and fill the fuel tank with the correct fuel mix or fuel type. Replace the fuel filter if it is clogged. Lastly, clean the carburetor and fuel lines if there is dirt in them.
