How to Choose the Right Spark Plug
Choosing the correct spark plug is essential for optimal lawn mower performance. It affects how well your engine starts and runs. Before making a purchase, consider the following factors.

Consider the electrode design. Single and multiple-electrode designs exist. Multiple electrodes often provide a better spark but might not be necessary for all mowers. - Gap Size
Check the required spark plug gap. Measure the gap and adjust if necessary using a gap tool. A properly gapped spark plug ensures efficient ignition and engine performance. - Brand Reputation
Choose from reputable brands like NGK, Bosch, and Champion. Quality brands often guarantee higher standards in materials and manufacturing processes, leading to enhanced reliability and performance.
By paying attention to these factors, you can select the right spark plug that suits your mower’s needs, ensuring reliable starts and efficient operation.
