Why Spark Plug Craftsman M110 Replacement is Necessary
From my experience, replacing the spark plug on my Craftsman M110 is essential to keep the engine running smoothly. Over time, the spark plug gets fouled with carbon deposits and dirt, which makes it harder for the engine to ignite the fuel-air mixture properly. This leads to poor performance, difficulty starting, and even increased fuel consumption.
I noticed that when the spark plug was worn out, my mower struggled to start and ran roughly. Once I replaced it with a new spark plug designed for the Craftsman M110, the engine fired up quickly and ran much more efficiently. Regular replacement ensures reliable ignition, better fuel efficiency, and prolongs the life of the engine. For me, it’s a small maintenance step that makes a big difference in how well my equipment performs.
My Buying Guides on Spark Plug Craftsman M110 Replacement
When I needed to replace the spark plug on my Craftsman M110, I quickly realized that picking the right replacement was more important than I first thought. To help you avoid the trial and error I went through, here’s my detailed guide based on my experience.
Understanding Your Craftsman M110 Spark Plug Requirements
Before buying a replacement spark plug, I checked the owner’s manual to confirm the exact specifications. The Craftsman M110 typically requires a spark plug with specific thread size, heat range, and electrode type. Using the wrong plug can cause poor engine performance or damage.
Key Features to Look For in a Replacement Spark Plug
- Correct Thread Size & Reach: The spark plug must fit perfectly into the engine cylinder. The Craftsman M110 usually uses a plug with a 14mm thread diameter and a reach of about 3/4 inch.
- Heat Range: I made sure to get a spark plug with the correct heat rating to avoid overheating or fouling. For the M110, a medium heat range is generally recommended.
- Electrode Material: Iridium or platinum electrodes can offer longer life and better performance compared to standard copper plugs. I opted for an iridium plug for durability.
- Gap Size: The electrode gap affects ignition. The M110 typically needs a gap around 0.030 inches. I always check and adjust the gap with a feeler gauge before installation.
Brands and Models I Recommend
From my research and personal use, these brands have been reliable replacements for the Craftsman M110:
- NGK: Their BPR5ES model fits well and performs consistently.
- Champion: Known for durability and easy availability.
- Bosch: High-quality with good heat range options.
Choosing a reputable brand gave me peace of mind about quality and compatibility.
Where to Buy Your Replacement Spark Plug
I found that local hardware stores sometimes don’t stock the exact plug I needed, so I turned to online retailers like Amazon and specialized small engine parts websites. These sources often have detailed compatibility info and reviews from other Craftsman M110 owners, which helped me confirm my choice.
Installation Tips From My Experience
- Always disconnect the spark plug wire before removing the old plug.
- Use a spark plug socket and ratchet to avoid damaging the plug or engine threads.
- Check and set the correct gap before installing the new plug.
- Screw in the plug by hand first to prevent cross-threading, then tighten to manufacturer torque specs.
- After installation, reconnect the spark plug wire securely.
Final Thoughts
Replacing the spark plug on my Craftsman M110 was straightforward once I had the right information. Picking a quality replacement spark plug with the correct specifications made a noticeable difference in engine starting and running smoothly. I hope my guide helps you make a confident choice and get your mower back to peak performance quickly!
