Why Craftsman M110 Spark Plug Replacement is Necessary
From my experience, replacing the spark plug on my Craftsman M110 is crucial for maintaining its performance. Over time, the spark plug can become dirty or worn out, which leads to poor ignition and makes the engine run rough or even stall. I noticed that after replacing the spark plug, my mower started much more easily and ran smoother, which saved me a lot of frustration during yard work.
Another reason I found replacement necessary is fuel efficiency. A worn spark plug causes incomplete combustion, meaning the engine uses more fuel than it should. By swapping in a fresh Craftsman M110 spark plug, I improved fuel economy and reduced emissions, which feels good both for my wallet and the environment.
Lastly, regular spark plug replacement helps prevent long-term engine damage. When the spark plug isn’t firing correctly, it puts extra strain on the ignition system and other engine parts. I learned that staying on top of this simple maintenance step extends the life of my mower and keeps it reliable season after season. Overall, replacing the spark plug is a quick and easy fix that makes a big difference in how my Craftsman M110 performs.
My Buying Guides on Craftsman M110 Spark Plug Replacement
When it comes to replacing the spark plug on my Craftsman M110 mower, I’ve learned that choosing the right part and following the proper steps can make a big difference in performance and longevity. Here’s my detailed guide to help you find and install the perfect spark plug replacement.
Why Replacing the Spark Plug Matters
Over time, the spark plug in my Craftsman M110 gets fouled or worn, which causes the engine to run rough, lose power, or even fail to start. Replacing it regularly ensures my mower runs smoothly and efficiently, saving me time and frustration during lawn care.
What to Look for in a Replacement Spark Plug
When I shop for a replacement, I pay attention to these key factors:
- Correct Model Number: The Craftsman M110 typically uses a specific spark plug model (often Champion RJ19LM or equivalent). Always check your mower’s manual or the existing plug to verify compatibility.
- Heat Range: The heat rating must match the original to avoid overheating or fouling. Using the wrong heat range can damage the engine.
- Electrode Gap: The gap should be pre-set or easily adjustable to the manufacturer’s specification (usually around 0.030 inches). I measure this with a feeler gauge before installation.
- Quality and Brand: I prefer well-known brands like Champion or NGK because they offer reliable performance and durability. Avoid cheap, generic plugs that may fail prematurely.
Where to Buy My Spark Plug Replacement
I usually find replacement spark plugs at:
- Local hardware or lawn equipment stores: Helpful if I want immediate purchase and expert advice.
- Online retailers like Amazon or manufacturer sites: Convenient for finding exact matches and reading reviews before buying.
- Authorized Craftsman parts dealers: Best for guaranteed compatibility and original OEM parts.
Tools I Use for Replacement
Before starting, I gather:
- A spark plug socket wrench (usually 5/8 inch)
- A ratchet or wrench handle
- A feeler gauge to check and adjust the gap
- A clean rag to wipe the area
- Anti-seize compound (optional, but helps prevent the plug from sticking)
Steps I Follow to Replace the Spark Plug
- Safety first: I disconnect the spark plug wire to prevent accidental starting.
- Remove the old plug: Using the spark plug socket and ratchet, I carefully unscrew and remove the old plug.
- Inspect the old plug: Checking for signs of wear, carbon buildup, or oil can help diagnose engine issues.
- Check and adjust the gap on the new plug: Using the feeler gauge, I ensure the gap matches the mower’s specs.
- Install the new plug: I screw it in by hand first to avoid cross-threading, then tighten snugly with the wrench (not too tight).
- Reconnect the spark plug wire: Making sure it’s secure.
Tips from My Experience
- Replace the spark plug annually or after about 25 hours of use for best performance.
- Clean the area around the spark plug before removal to avoid debris falling into the engine.
- If the engine is hard to start or runs rough after replacement, double-check the gap and spark plug wire connection.
- Keep a spare spark plug on hand during mowing season for quick replacement.
By following these guidelines, I’ve kept my Craftsman M110 running reliably and smoothly. I hope this helps you maintain your mower with confidence!
