When it comes to maintaining your lawn mower, cleaning the spark plugs is a crucial task that can greatly impact the performance of your machine. This simple maintenance job can help ensure that your lawn mower starts easily and runs smoothly throughout the mowing season.
To clean your lawn mower spark plugs effectively, you will need a few basic tools and supplies. Start by gathering a wire brush, a spray-on plug cleaner specifically designed for spark plugs, and a sturdy knife for scraping off tough deposits.
Before you begin, it is important to disconnect the spark plug wire to prevent any accidental starts while you are working on the mower. Once the spark plug wire is removed, use the wire brush to gently clean the spark plug, removing any dirt, oil, or deposits that may have accumulated.
If the spark plug is heavily soiled or has stubborn deposits, you can use the spray-on plug cleaner to dissolve and remove any build-up. Be sure to follow the manufacturer’s instructions when using the cleaner to ensure safe and effective cleaning.
In some cases, you may encounter tough deposits that are difficult to remove with a brush or cleaner. In these situations, a sturdy knife can be used to carefully scrape off any remaining debris from the spark plug. Take care not to damage the spark plug during this process.
Once you have cleaned the spark plug thoroughly, inspect it carefully for any signs of damage or wear. Look for cracks, corrosion, or other issues that may indicate the need for a replacement. If the spark plug shows significant wear, it is best to replace it with a new one.
After cleaning and inspecting the spark plug, it is important to properly gap the electrode to ensure optimal performance. Use a gapping tool to adjust the distance between the electrode and the ground electrode according to the manufacturer’s specifications.
Finally, before re-installing the spark plug, apply a small amount of anti-seize compound to the threads to prevent the plug from seizing in the engine. Carefully tighten the spark plug by hand, then use a spark plug wrench to secure it in place.
Once the spark plug is securely in place, reattach the spark plug wire and start your lawn mower to ensure that the engine is running smoothly. If you notice any issues or irregularities, double-check the spark plug installation and cleaning to address any potential problems.
