Choosing the Right Spark Plugs:
Once you’ve identified your preferred purchasing location, the next step is selecting the correct spark plugs for your lawnmower. Here’s a breakdown of key factors to consider:
1. Mower Model and Engine Type:
The most crucial factor is compatibility. Spark plugs are designed to work specifically with certain mower models and engine types. Consult your owner’s manual or the sticker located on your engine for the recommended spark plug specifications.
2. Spark Plug Type:
Different types of spark plugs exist, each suited for various applications. Common types include:
- Copper Spark Plugs: Affordable and generally reliable, offering good performance for most lawnmower engines.
- Platinum Spark Plugs: Longer lifespan and increased durability than copper spark plugs, offering improved performance and fuel efficiency.
- Iridium Spark Plugs: Provide the most extended lifespan and enhanced durability, offering superior ignition performance and improved fuel efficiency.
3. Heat Range:
The heat range refers to the spark plug’s ability to dissipate heat. It’s crucial to select a spark plug with a heat range suitable for your engine. A lower heat range signifies faster heat dissipation, suitable for hotter operating conditions. Conversely, a higher heat range indicates slower heat dissipation, suitable for colder operating conditions.
4. Gap Size:
The gap between the spark plug’s electrodes is crucial for proper ignition. The recommended gap size is typically specified in your owner’s manual. Using the wrong gap size can lead to poor performance and engine damage.
Installing Spark Plugs:
Once you’ve obtained the correct spark plugs, you can install them yourself with a few simple steps:
1. Prepare Your Tools:
Gather the necessary tools for the installation process:
- Socket wrench: Choose a socket wrench compatible with your spark plug size.
- Spark plug gap tool: A spark plug gap tool is essential for adjusting the spark plug gap to the manufacturer’s specifications.
2. Disconnect the Spark Plug Wire:
Locate the spark plug wire connected to the spark plug. Disconnect it by pulling gently on the wire’s boot.
3. Remove the Old Spark Plug:
Use the socket wrench to loosen and remove the old spark plug. Be careful not to cross-thread or damage the spark plug threads.
4. Install the New Spark Plug:
Thread the new spark plug into the spark plug hole, ensuring it’s seated properly. Use the socket wrench to tighten the spark plug until it’s snug but not overly tight.
5. Set the Spark Plug Gap:
Use the spark plug gap tool to adjust the gap between the spark plug’s electrodes to the manufacturer’s specifications.
6. Reconnect the Spark Plug Wire:
Carefully reconnect the spark plug wire to the new spark plug. Ensure the boot fits securely and makes good contact.

If you can’t find your manual, you can often find this information on the spark plug itself or on a sticker attached to your lawn mower’s engine. You can also use a spark plug cross-reference chart to find a compatible replacement.
How often should I replace my lawn mower spark plug?
The recommended replacement interval for lawn mower spark plugs can vary depending on the model and usage. However, it’s generally recommended to replace the spark plug every 100 hours of operation or at least once per year.
If you notice any signs of wear or damage on your spark plug, such as a worn electrode or a cracked insulator, you should replace it immediately. A worn spark plug can cause your lawn mower to run poorly, start hard, or even stall.
What are the signs that my lawn mower spark plug needs to be replaced?
There are several signs that your lawn mower spark plug might be nearing the end of its life. These include:
- Difficulty starting the engine
- The engine running rough or sputtering
- A decrease in power or performance
- Black smoke coming from the exhaust
- A burning smell
If you notice any of these symptoms, it’s a good idea to inspect the spark plug and replace it if necessary.
Can I replace my lawn mower spark plug myself?
Yes, replacing a lawn mower spark plug is a relatively simple task that most DIY enthusiasts can handle. However, it’s important to follow safety precautions and consult your owner’s manual for specific instructions.
Before you begin, make sure the engine is cool and disconnected from the power source. You’ll need a wrench to remove the spark plug and a gap gauge to check the gap.
How do I properly gap a lawn mower spark plug?
Gapping a spark plug is important for ensuring optimal performance. The spark plug gap refers to the distance between the electrode and the center electrode. If the gap is too wide, the spark may not be strong enough to ignite the fuel mixture. If the gap is too narrow, it can cause the spark plug to foul and overheat.
To gap a spark plug, you’ll need a spark plug gap gauge. These gauges are available at most auto parts stores and come in different sizes. Simply insert the gauge into the spark plug gap and adjust the electrode position until the gauge fits snugly.
What should I do with my old lawn mower spark plug?
Once you’ve removed the old spark plug, it’s important to dispose of it properly. Spark plugs contain hazardous materials, such as lead and cadmium, so they shouldn’t be thrown in the trash.
You can usually recycle old spark plugs at your local auto parts store or recycling center. Alternatively, you can remove the electrode and insulator and discard the remaining metal parts in the trash.
