Why Choosing the Right Spark Plug for My Craftsman M110 Lawn Mower Is Necessary
When I first started maintaining my Craftsman M110 lawn mower, I quickly learned how important the right spark plug is for its performance. The spark plug is the heart of the engine’s ignition system—it ignites the fuel-air mixture to keep the engine running smoothly. Using the correct spark plug ensures my mower starts easily every time and runs efficiently without misfires or sputtering.
I also found that the right spark plug helps prolong the engine’s life. If I use a plug that isn’t designed for the Craftsman M110, it can cause incomplete combustion or fouling, which leads to rough idling and poor fuel economy. Over time, this can damage the engine or lead to costly repairs. So, picking the correct spark plug is not just about immediate performance—it’s about protecting my investment in the mower and making sure it lasts for many seasons.
Finally, using the recommended spark plug means I spend less time troubleshooting and more time mowing. I don’t have to worry about unexpected breakdowns or difficult starts, which makes my lawn care routine much smoother. For me, the right spark plug is a simple but crucial part of keeping my Craftsman M110
My Buying Guides on Which Spark Plug To Get For Craftsman M110 Lawn Mower
When I was looking to replace the spark plug on my Craftsman M110 lawn mower, I realized that choosing the right one is crucial for optimal performance and longevity of the engine. Here’s what I learned and how I decided on the best spark plug for my mower.
Understanding the Importance of the Spark Plug
The spark plug is the heart of the mower’s ignition system. It ignites the air-fuel mixture inside the engine cylinder to start and keep the mower running smoothly. Using the wrong spark plug can cause poor performance, difficulty starting, or even engine damage. I always make sure to get the correct type to avoid these issues.
Check the Manufacturer’s Recommendation
The first thing I did was consult my Craftsman M110 owner’s manual. Craftsman usually specifies the exact spark plug model recommended for their engines. For the M110, the typical spark plug recommended is the Champion RJ19LM or an equivalent. This ensures compatibility in size, heat range, and performance.
Key Features to Look For
When picking a spark plug, I focus on these features:
- Thread Size and Reach: The spark plug must fit perfectly in the engine cylinder head. For the M110, the thread size is usually 14mm with a 3/4 inch reach.
- Heat Range: This indicates how quickly the spark plug can dissipate heat. The recommended heat range ensures the plug doesn’t overheat or foul. The RJ19LM has the right heat range for the M110 engine.
- Electrode Type: I prefer a copper core or standard electrode for reliable ignition. Some go for platinum or iridium for longer life, but for a mower like the M110, a good quality standard plug works fine and is more cost-effective.
- Gap Size: The gap between the electrodes affects the spark quality. The Craftsman M110 typically requires a gap of around 0.030 inches. Some plugs come pre-gapped, but I always double-check and adjust if needed.
My Favorite Spark Plug Choices for Craftsman M110
Based on my experience and what I found recommended, these are the spark plugs I trust:
- Champion RJ19LM: This is the OEM recommended plug. It fits perfectly and delivers consistent performance.
- NGK BPR5ES: A reliable aftermarket option with similar specs and great user reviews.
- Briggs & Stratton 796106: Compatible with many small engines, including Craftsman M110, offering good durability.
Additional Tips Before Buying
- Always buy from reputable brands or authorized dealers to avoid counterfeit parts.
- Inspect the old spark plug for wear or damage before replacement; it can give clues about engine condition.
- Replace the spark plug annually or after about 100 hours of use for best mower performance.
- Keep a spark plug wrench handy for easy installation and removal.
Final Thoughts
Choosing the right spark plug for my Craftsman M110 lawn mower made a noticeable difference in how smoothly my mower starts and runs. I recommend sticking to the manufacturer’s specs and picking a quality plug like the Champion RJ19LM. It’s a small part, but it plays a big role in the health of your mower’s engine.
