The importance of a well-maintained lawnmower cannot be overstated. A lawnmower is an essential tool for any homeowner, providing a neat and tidy appearance for their lawn. However, a lawnmower that is not properly maintained can lead to a range of problems, including poor performance, reduced efficiency, and even damage to the machine itself. One of the most critical components of a lawnmower is the spark plug. A faulty spark plug can prevent the engine from starting, or cause it to run rough and unevenly. In this article, we will explore the importance of testing a lawnmower spark plug, and provide a step-by-step guide on how to do it.
Why Test a Lawnmower Spark Plug?
A spark plug is responsible for igniting the fuel-air mixture in a lawnmower’s engine, allowing it to run smoothly and efficiently. Over time, a spark plug can become worn out or fouled with debris, which can prevent it from functioning properly. Testing a lawnmower spark plug is essential to ensure that it is functioning correctly, and to identify any potential issues before they become major problems.
How to Test a Lawnmower Spark Plug
Testing a lawnmower spark plug is a relatively simple process that can be completed with a few basic tools. Here’s a step-by-step guide on how to do it:
Step 1: Locate the Spark Plug
The spark plug is typically located on the side of the lawnmower’s engine. It may be covered with a spark plug cover or boot, which will need to be removed before testing. Use a spark plug socket to remove the spark plug from the engine.
Step 2: Inspect the Spark Plug
Once the spark plug has been removed, inspect it for any signs of wear or damage. Look for any cracks, corrosion, or fouling on the spark plug’s electrode or insulator. If the spark plug appears to be damaged, it may need to be replaced.
Step 3: Use a Spark Tester
A spark tester is a simple tool that is used to test the spark plug’s ability to produce a spark. The tester consists of a small metal probe that is attached to a spark plug wire. When the spark plug is connected to the tester, it will produce a spark if it is functioning properly. If the spark plug does not produce a spark, it may be faulty and need to be replaced.

Step 4: Check the Spark Plug Gap
The spark plug gap is the distance between the spark plug’s electrode and the spark plug’s insulator. If the gap is too small or too large, it can prevent the spark plug from functioning properly. Use a spark plug gap gauge to check the gap and adjust it as necessary.
Step 5: Replace the Spark Plug
If the spark plug is found to be faulty or damaged, it will need to be replaced. Use a new spark plug that is compatible with the lawnmower’s engine, and follow the manufacturer’s instructions for installation.
Common Issues with Lawnmower Spark Plugs
Lawnmower spark plugs are prone to a range of issues, including fouling, corrosion, and wear. Here are some common issues that can affect a lawnmower spark plug:
- Fouling: A spark plug can become fouled with debris, such as grass clippings or dirt, which can prevent it from functioning properly.
- Corrosion: A spark plug can corrode over time, which can prevent it from producing a spark.
- Wear: A spark plug can wear out over time, which can affect its ability to produce a spark.
- Carbon buildup: A spark plug can become clogged with carbon deposits, which can prevent it from functioning properly.
