Steps to Changing the Spark Plug
Remove the Spark Plug Wire: Locate the spark plug wire, which is usually pressed onto the connector. You can use a puller or pinch it to remove. Remove the Old Spark Plug: Fit the proper deep socket size around the spark plug (5/8 or 11/16 or 3/4 inch, according to your model) and use a socket wrench to unscrew the plug. Inspect the Spark Plug: After removing the old plug, inspect it for wear and tear. Check the air gap and the overall condition. This will help you determine the correct replacement. Install the New Spark Plug: If you have anti-seize compound, apply it to the threads of the new plug to prevent corrosion and make the removal process easier next time. Install the new plug by hand until it is firmly seated, then tighten it about a quarter turn. Reattach the Spark Plug Wire: Simply put the spark plug wire back onto the new plug and secure it.Tips for Maintaining Your Mower
To ensure that your push mower performs at its best, it's important to regularly check and maintain the spark plug. Here are some additional tips:
Check the spark plug gap: A spark plug with an incorrect gap can cause misfiring. You can adjust the gap using a spark plug gap tool. Verify the spark plug type: Ensure that the new spark plug you purchase is the correct type for your mower model. Consult the owner's manual for specific requirements. Use quality materials: Investing in high-quality spark plugs and anti-seize compound can extend the life of your mower and ensure efficient operation.Common Mistakes to Avoid
Following these steps correctly is important, but many people make common mistakes when changing the spark plug. Here are some pitfalls to avoid:
Using the wrong tools: Always use the appropriate tools, such as a deep socket, to ensure the job is done safely and effectively. Failing to tighten the plug properly: Under-tightening or over-tightening can cause the spark plug to become loose or stripped. Tighten it about a quarter turn to avoid both issues. Using a hot engine: Attempting to work on a hot engine can be dangerous and should be avoided for safety reasons.Conclusion
