This combustion is what drives the pistons and ultimately makes the lawn mower’s engine roar to life. Without a properly functioning spark plug, the engine won’t start or run efficiently, resulting in sluggish performance and frustration for the user. So, next time you take your lawn mower out of the shed, remember to give the spark plug the attention it deserves.

Keep it clean, check for any signs of damage, and replace it when necessary. Trust me, your lawn mower will thank you for it!

This small but mighty device plays a crucial role in igniting the fuel-air mixture in your engine, so it’s important to choose the right size for your specific mower.

Commonly, lawn mowers with engines measuring under 50cc use spark plugs with a 14mm thread diameter. However, the length and heat range can vary depending on the brand and model of your mower.
