The spark plug plays a big role in starting, smooth running, and fuel efficiency, so I always make sure I confirm the mower model and engine details before buying.
What I Look For First
The first thing I check is the owner’s manual or the engine label. In my experience, this is the safest way to identify the correct spark plug type. For the Craftsman M110 110cc mower, I don’t rely only on the mower name because different production runs can use different engine parts.
Why Spark Plug Type Matters
I’ve learned that using the wrong spark plug can cause hard starting, poor performance, misfiring, or even engine damage over time. A proper spark plug helps my mower start easier, run cleaner, and cut more consistently. It also saves me from unnecessary maintenance issues later.
Things I Check Before Buying
- Thread size and reach: I always verify the plug fits the engine head correctly.
- Heat range: I make sure it matches the mower engine’s needs so it doesn’t run too hot or too cold.

My Buying Tips
When I shop for a spark plug, I prefer buying from a reliable seller that lists full compatibility details. I also like to keep the old spark plug as a reference until I confirm the new one matches. If I’m unsure, I cross-check the part number with the mower manual or the engine manufacturer’s parts list.
Signs I Need a New Spark Plug
I usually replace the spark plug if my mower is hard to start, idles rough, loses power, or burns more fuel than usual. If I remove the plug and see heavy carbon buildup, wear, or corrosion, I treat that as a clear sign it’s time for a replacement.
Installation Advice I Follow
Before installing a new spark plug, I always let the engine cool down. I clean around the plug area first so dirt doesn’t fall into the cylinder. Then I install the plug carefully by hand before tightening it to avoid cross-threading. If the plug needs a gap adjustment, I set it according to the engine’s recommendation.
My Final Thoughts
For me, buying the right spark plug for a Craftsman M110 110cc lawn mower comes down to careful checking and not rushing the purchase. Once I match the correct type, my mower starts better and runs more reliably. That small part makes a big difference in how well the machine performs.
