Maintaining your lawn mower’s optimal performance requires knowing essential components, and one such crucial part is the spark plug.
The spark plug is a small but mighty element that plays a vital role in igniting the fuel-air mixture, powering the engine to start and run smoothly.
In this article, we’ll guide you through the process of finding the spark plug on your lawn mower and provide insights into its maintenance.
Where is Spark Plug on Lawn Mower?
The spark plug’s location can vary based on the lawn mower’s design and model. However, it’s generally positioned near the engine’s cylinder head. To locate it, follow these steps:
Ensure Safety First: Before beginning any maintenance, ensure the lawn mower is turned off and disconnected from any power source.
Check the Engine Cover: Most lawn mowers have a protective cover over the engine. This cover is usually secured with screws. Use a screwdriver to remove these screws and lift off the cover.
Identify the Cylinder Head: Once the engine cover is removed, you’ll see the cylinder head – the upper part of the engine. The spark plug is usually positioned on the side of the cylinder head.
Inspect the Spark Plug Wire: The spark plug is connected to a wire. Follow this wire to locate the spark plug’s tip – the part that enters the cylinder head.
Keep in mind that the spark plug’s precise location might differ depending on whether your lawn mower is a push mower, self-propelled, or a riding mower. Always refer to your owner’s manual for accurate guidance.
Maintenance of the Spark Plug: Ensuring Optimal Performance
The spark plug’s performance directly impacts your lawn mower’s efficiency and fuel consumption. Regular maintenance can prolong its life and prevent issues. Here are steps to maintain the spark plug:
Cleaning: Over time, carbon deposits can accumulate on the spark plug’s electrode. Use a wire brush or a special spark plug cleaning tool to remove these deposits gently. Make sure not to damage the electrode.
Inspection: Regularly inspect the spark plug for signs of damage, such as cracks or erosion. If you notice any issues, it’s best to replace the spark plug promptly.
Gap Adjustment: The gap between the spark plug’s electrode and the grounding strap affects its performance. Refer to your manual to determine the correct gap measurement and use a gap tool to adjust it if needed.
Replacement: Spark plugs have a limited lifespan. If cleaning and adjustment don’t improve performance, replace the spark plug with a new, compatible one.
