How to Fix Mower Wont Turn Over Unless Spark Plug Is Out Clean Or Replace Spark Plug If your mower won't turn over unless the spark plug is out, start by inspecting the spark plug. A dirty or fouled spark plug can prevent your mower's engine from starting. To fix this issue, carefully remove the spark plug and clean off any debris. If cleaning doesn't work, replace the spark plug with a new one to ensure proper ignition. Reconnect And Tighten Spark Plug If the spark plug appears to be seated correctly but the engine still doesn't start, reconnect and tighten the spark plug to ensure a proper connection. Loose or disconnected spark plugs can lead to starting issues in your mower. Ensure the spark plug is securely fastened to promote efficient ignition. Clean Or Replace Air Filter Another common cause of a mower not turning over is a dirty air filter. To address this, clean or replace the air filter. A clogged or dirty air filter can restrict airflow to the engine, causing starting problems. Regular maintenance of the air filter is essential to ensure optimal performance of your mower. Tap The Carburetor To Help Fuel Flow If fuel is not reaching the engine, tapping the side of the carburetor can help facilitate the flow of gas. Gently tapping the carburetor can dislodge any potential blockages, allowing fuel to reach the engine and promoting proper ignition. If tapping doesn't resolve the issue, consider seeking a professional for further assistance. Consider Replacing Fuel Filter If the above steps do not resolve the starting issue, consider replacing the fuel filter. A clogged or old fuel filter can impede the flow of fuel to the engine, leading to difficulties in starting. By replacing the fuel filter, you can ensure a consistent and clean fuel supply for your mower's engine.
