As the summer months approach, many homeowners and gardeners rely on their push mowers to keep their lawns well-manicured. However, like any machine, these mowers require regular maintenance to ensure they continue to run efficiently and effectively. One crucial aspect of push mower maintenance is changing the spark plug. A faulty spark plug can cause a range of problems, from poor engine performance to complete engine failure. In this comprehensive guide, we will walk you through the steps to change a spark plug in a push mower, highlighting the importance of this task and providing detailed instructions to ensure a successful outcome.
Why Change a Spark Plug in a Push Mower?
A spark plug is a critical component of a push mower’s engine, responsible for generating the spark that ignites the fuel-air mixture. Over time, the spark plug can become worn out, leading to a range of issues. Some common problems associated with a faulty spark plug include:
- Poor engine performance
- Difficulty starting the engine
- Engine stalling or sputtering
- Reduced fuel efficiency
- Increased emissions
Regularly changing the spark plug can help prevent these issues and ensure your push mower runs smoothly and efficiently. It’s also a cost-effective way to maintain your mower, as replacing a spark plug is a relatively inexpensive task compared to repairing or replacing the entire engine.
Tools and Materials Needed
To change a spark plug in a push mower, you’ll need the following tools and materials:
- Spark plug socket (compatible with your mower’s spark plug type)
- Spark plug wrench (optional)
- Spark plug gap gauge (optional)
- New spark plug (compatible with your mower’s spark plug type)
- Spark plug cleaner (optional)
- Work light (optional)
Make sure to consult your mower’s owner’s manual for specific recommendations on the type of spark plug and socket required for your model.
Step 1: Prepare the Mower
Before starting the spark plug change, make sure the mower is in a well-ventilated area and the engine is cool. Remove any debris or obstructions from around the spark plug area to ensure easy access.

Step 3: Install the New Spark Plug
Insert the new spark plug into the spark plug well, ensuring it’s properly seated and aligned. Use a spark plug socket to tighten the spark plug in a clockwise direction.
Check the Spark Plug Torque
Use a torque wrench to check the spark plug torque, ensuring it’s within the recommended specification. Consult your mower’s owner’s manual for the recommended torque value.
Step 4: Reconnect the Spark Plug Wires
