A spark plug is a vital component of a lawn mower engine, as it provides the spark that ignites the fuel and air mixture in the engine's combustion chamber, allowing the engine to run.
When selecting a spark plug for your lawn mower, it's essential to consider the make and model of your mower, as well as the manufacturer's recommendations. Spark plugs come in different sizes and heat ranges, so it's crucial to choose the right one for your engine to ensure proper combustion.
Most lawn mower spark plugs are made of steel or ceramic materials, and they come in various electrode configurations. Some of the most common configurations are the standard plug, the resistor plug, and the platinum plug. Standard plugs are the most basic and least expensive option, while platinum plugs are more durable and long-lasting.
It's generally recommended to change your lawn mower's spark plug at least once a year or after every 100 hours of use. This will ensure that your mower's engine runs smoothly and efficiently, and it will help to prevent problems such as hard starting, misfiring, and reduced power.
