If your Mac allister Lawn Mower engine won't start, it might be due to several reasons. First, ensure you have enough fuel in the tank by adding fuel. Check if the spark plug is wet and dry it if necessary. Inspect the spark plug for damage and replace it if needed. Make sure the spark plug connector is properly attached and the spark plug itself is tightened to 25-30 Nm with the gap between electrodes set to 0.7-0.8 mm. Also, verify that the cutting height adjustment lever is in the correct position. Clean the air filter. If you have an electric start, ensure the battery is charged and the starter wire is connected.
