Craftsman Leaf Blower Spark Plug Parts

Craftsman Leaf Blower Spark Plug Parts

A fouled or worn spark plug is one of the quickest fixes for a Craftsman leaf blower that won't start or runs rough. Whether your blower sits seasonally or gets regular use, the spark plug takes the brunt of old fuel, carbon buildup, and electrode wear. A fresh OEM spark plug restores reliable ignition and smooth idle.

Craftsman leaf blowers use specific spark plug types depending on the engine — typically Champion or NGK plugs in the correct heat range. Using the right OEM spec prevents hard starts and running issues that mimic carburetor problems. Find the exact spark plug for your Craftsman model by entering your model number below.

• Won't start: Fouled plug, wet plug, or corroded electrode
• Runs rough or sputters: Worn gap, carbon buildup, or wrong heat range
• Engine floods: Wet spark plug from excess fuel; dry and replace plug
• Loss of power: Electrode erosion; plug is past service life
• Seasonal storage: Replace plug before winter storage and spring startup

Craftsman Leaf Blower Spark Plug FAQ

What spark plug does my Craftsman leaf blower use?

Craftsman leaf blowers typically use Champion RJ19LM or NGK BR2LM spark plugs, but heat range varies by engine type and year. The safest approach is to find your model number on the blower frame and look up the exact OEM specification. Repair Clinic's model-number tool will show you the correct plug, gap setting, and heat range to order.

Can I use any spark plug in a Craftsman leaf blower?

Not without risk. Using the wrong heat range can cause hard starting, fouling, or overheating. A "cold" plug (higher heat range) works best in high-load engines; a "hot" plug (lower heat range) prevents fouling in low-speed, low-load work like leaf blowing. Stick with the OEM specification for reliable cold starts and smooth running.

How often should I replace my Craftsman leaf blower spark plug?

For seasonal use, replace the spark plug once per year before you store the blower (fall or spring). For regular use, inspect it every 25 to 50 operating hours — if the electrode is black, wet, or severely eroded, replace it. Stale fuel and sitting over winter are the most common causes of fouled plugs.

How do I know if my spark plug is bad?

Pull the spark plug and look at the electrode. A good plug has a tan/light brown color and a tight gap (usually 0.025" — 0.030" depending on model). Black/sooty, wet, or heavily pitted electrodes mean replace it. If the plug looks OK but the blower still won't start, the carburetor is likely the next culprit.

Craftsman Leaf Blower Model Number: Where to Look

On Craftsman leaf blowers, look for the model number on a label attached to the main housing near the engine, or along the blower's frame. You may need to brush away dirt or remove the collection bag to see the label clearly. The number often begins with digits such as 358 and is different from the engine or spark plug number. Enter it in the model number search to pull up the parts matched to your unit, across every part category. That means fewer wrong orders and a faster repair.
