How to Change a Lawn Mower Spark Plug

Tired of pulling your back out trying to start your lawn mower, only to have it sputter and die? Perhaps your mower needs a new spark plug – the device that creates the electrical spark that ignites the fuel in your engine. If the spark plug is worn or bad, it can cause the mower to run rough or not start at all.

Check the spark plug annually as part of your regular lawn mower maintenance. Sometimes the spark plug can be cleaned and adjusted by resetting the spark gap at the end of the plug. If not, it will need to be replaced.

Even if you’re not mechanically inclined, you can replace a spark plug in a matter of minutes for less than $5, which makes a world of difference in helping your lawn mower start and run properly. Read on to find out how to go about it.
