- Insert the New Spark Plug: Carefully thread the new spark plug into the engine by hand. Avoid cross-threading.
- Tighten the Plug: Once hand-tight, use the torque wrench to tighten the spark plug to the recommended torque specification, generally between 12 to 15 ft-lbs.
- Reattach the Wire: Place the spark plug wire back onto the new spark plug. Ensure it clicks into place securely.
Completing these steps properly enhances your Honda lawn mower’s performance and efficiency.
Common Mistakes to Avoid
When changing the spark plug on your Honda lawn mower, avoid these common mistakes for a smoother experience:
- Neglecting Safety Gear
Don’t forget to wear safety glasses. Protect your eyes from debris that may fly when removing the spark plug. - Using Incorrect Tools
Avoid using the wrong size socket for the spark plug. This can strip the plug or damage the threads. Always use the specified socket for your model. - Inadequate Gap Check
Don’t skip checking the spark plug gap. An incorrect gap can lead to poor performance. Use a feeler gauge to ensure the gap meets manufacturer specifications. - Forgetting to Disconnect the Wire
Always disconnect the spark plug wire before starting work. Neglecting this step can lead to accidental starts and potential injury. - Over-tightening the Spark Plug
Avoid over-tightening the new spark plug. This can damage the threads in the engine. Consult your torque wrench for the recommended tightening specifications. - Ignoring Maintenance
Don’t overlook regular maintenance on your lawn mower. Clean the air filter and ensure proper fuel levels for optimal performance. - Rushing the Process
Take your time when changing the spark plug. Rushing increases the likelihood of mistakes. Follow the steps methodically for a successful replacement.

Tips for Maintaining Your Lawn Mower
- Regular Inspection: Check your lawn mower weekly for any signs of wear. Look for frayed cables, loose parts, and oil leaks. Early detection prevents major issues.
- Clean the Mower: Remove grass clippings and debris after each use. Use a clean rag or a brush to keep the blades and undercarriage clear. This practice promotes better performance.
- Change the Oil: Change the oil every 50 hours of operation or at least once a season. Fresh oil ensures optimal engine performance and longevity.
- Replace Air Filters: Inspect and replace air filters regularly. A clean filter keeps dirt and debris from entering the engine, enhancing efficiency and engine life.
- Sharpen Blades: Sharpen the mower blades every 20 to 25 hours of use. Dull blades tear grass rather than cut it, leading to stress on the grass and unhealthy lawns.
- Check Belts and Cables: Examine belts and cables for signs of wear or fraying. Replace them if you spot any damage. This action keeps your mower functioning smoothly.
- Store Properly: Store your mower in a dry, sheltered spot. Use a mower cover to protect it from dust and moisture. This practice extends its lifespan.
- Fuel Maintenance: Use fresh gasoline and consider adding a fuel stabilizer if storing the mower for more than a month. This will prevent fuel degradation and ensure easy starting.
- Follow the Manual: Refer to your owner’s manual for specific maintenance schedules and recommendations. This ensures you adhere to the manufacturer’s guidelines for optimal performance.
Maintaining your lawn mower with these tips promotes better performance, efficiency, and a longer lifespan.
