Hard starts, sputtering, and weak power are all red flags your plug needs replacing. Check our full inventory of Toro lawn mower parts — we ship same-day and help ensure fit. Have your model number handy to find the exact replacement.

• Won't start or hard starting — spark plug gap wear or carbon buildup blocks ignition
• Rough idle and sputtering — fouled electrode prevents clean combustion
• Loss of power during mowing — weak spark from worn plug terminals
• Black sooty deposits on plug — running too rich, plug needs cleaning or replacement
• Wet plug after sitting — fuel leak or ignition failure, swap the plug first

Toro Lawn Mower Spark Plug Parts: Questions & Troubleshooting

Why does my Toro mower spark plug foul so quickly?

Toro engines run rich if your air filter is clogged, the carburetor needs cleaning, or fuel sits unused in the tank over winter. A fouled plug burns black carbon fast. Always start with a fresh air filter and clean fuel — then replace the plug if it's still dark or wet.

What's the difference between a spark plug and a spark plug boot?

The spark plug screws into the engine head and ignites fuel. The boot is the rubber cap on the wire that connects to the plug top and delivers the spark. Both wear out — if your Toro won't spark even with a new plug, the boot or wire may be cracked or loose.

How do I find my Toro mower model number for the right spark plug?

Look on the frame or under the seat for a metal tag with model, serial, and engine type. Toro uses different plugs for 4-cycle vs. 2-cycle engines, so model number is essential. Once you have it, we'll match you to the exact OEM plug and boot your engine needs.

Can I use a standard spark plug instead of genuine Toro?

While some generic plugs fit, OEM Toro plugs are engineered for your engine's specific heat range and gap. Genuine parts start easier, burn cleaner, and last longer. Since we stock OEM at the same price as aftermarket, there's no reason to compromise — order the genuine plug.
