Maximize Your Lawn Mower’s Performance: A Guide to Spark Plug Maintenance

Spark plugs may seem small, but they play a crucial role in your lawn mower’s performance. A worn-out or faulty spark plug can cause starting and running issues in your mower’s engine. Regularly checking and replacing spark plugs is essential for smooth operation.

Manufacturers typically suggest replacing lawn mower spark plugs every two years. However, for optimal engine performance, it’s advisable to change them annually or after every 30 engine hours. Incorporating spark plug replacement into your yearly maintenance routine ensures consistent performance. 

What tools do I need to change spark plugs?

To change your mower’s spark plugs, you will need basic tools such as a regular socket or wrench, a spark plug socket, and a spark plug gap gauge. The gap gauge ensures precise installation according to manufacturer specifications.
