How do I know if my lawnmower needs a new spark plug?

A spark plug is a small component in your lawnmower that can have a big impact on its performance. If your spark plug is old or damaged, it can cause your mower to run poorly and even stall out. So how do you know if your lawnmower needs a new spark plug?

One sign that your spark plug may need to be replaced is if it’s visibly dirty or covered in oil. Another indication is if the metal electrode at the tip of the plug is worn down. If either of these things is happening, it’s time for a new spark plug.

Replacing the sparkplug isn’t difficult, but it’s something you’ll want to do before trying to start up the lawnmower again. Consult your owner’s manual for instructions on how to replace the Spark Plug and make sure you select one that matches the specs of your current model – there are many different types and sizes available!
