In my experience, the right spark plug makes starting easier, keeps the engine running smoother, and helps the mower last longer. Using the wrong plug can cause hard starts, poor performance, or even engine damage.
What Spark Plug Type I Look For
For the Craftsman M110 110cc mower, I always check the owner’s manual or engine label first. In many cases, this mower uses a small-engine spark plug such as an NGK BPMR7A or an equivalent model, but I never buy based on guesswork alone. I verify:
- Thread size
- Reach length
- Heat range
- Electrode style
- Gap setting
I’ve found that even a plug that looks similar may not perform correctly if one of these details is off.
How I Confirm Compatibility
Before I buy, I compare the spark plug specifications with my mower’s engine requirements. I usually:

- Read the engine model number
- Match the old spark plug number

This step saves me from buying the wrong part and having to return it later.

When I shop for a spark plug, I look for these things:
- Exact replacement fit for the Craftsman M110 110cc engine
- Pre-gapped or adjustable gap depending on the plug
- Trusted brand like NGK, Champion, or OEM-listed parts
- Rust-resistant packaging so the plug stays in good condition
- Clear product description with engine compatibility
I prefer buying from sellers who list the plug type clearly instead of using vague “fits many models” claims.
Signs I Need a New Spark Plug
I usually replace the spark plug if I notice:
- Hard starting
- Rough idling
- Reduced power
- Misfiring
- Excessive fuel use
- A dirty, worn, or fouled old plug
If my mower has been sitting unused for a long time, I often replace the plug as part of basic maintenance.
My Tips for Getting the Best Value
I don’t always choose the cheapest spark plug. Instead, I look for a balance of price and quality. My best tips are:
- Buy from a reliable brand
- Compare OEM and aftermarket options
