How to Check Spark Plug on Lawn Mower: Essential Maintenance Guide

Are you having trouble starting your lawn mower? Is it sputtering and struggling to get going? Before you start panicking and calling a professional, take a moment to check your spark plugs. These small but mighty components play a crucial role in the operation of your lawn mower, and if they are dirty or damaged, they can cause all sorts of problems. Just like the spark plugs in your car, the spark plugs in your lawn mower create the spark that ignites the fuel-air mixture in the engine.

This ignition is what allows the engine to start and run smoothly. Over time, however, these spark plugs can become fouled with dirt, oil, and carbon deposits. When this happens, the spark can be weakened or prevented altogether, leading to misfires, poor engine performance, and difficulty starting the mower.
