When to Replace Your Lawn Mower Spark Plug

For optimal performance, it’s recommended to replace the spark plug in your lawn mower once per season or after every 100 hours of use. Signs that your spark plug may need replacement include difficulty starting, reduced engine power, misfiring, or a rough idle. You can check for wear by inspecting the plug tip for buildup, corrosion, or a damaged electrode. Keeping a fresh spark plug ensures reliable ignition, efficient fuel combustion, and smooth engine performance.
