  • I needed a basic starter button for an older truck and this did exactly what I wanted. The switch feels much more solid than the cheap plastic ones I've used before. Installation was straightforward and the terminals held the wiring securely. So far it has worked every time.

  • Used this on a project car where I wanted a separate push-button starter. Nice heavy-duty feel and the rubber cap is a big plus since the vehicle gets used outdoors. Press it, the starter engages, release it and it stops. Simple and reliable.

  • My old starter button finally gave out, so I replaced it with this one. It mounted cleanly and feels sturdy once tightened down. The protective cap fits well and keeps the button covered when I'm not using it. Very happy with it for the price.

    Small gasoline engines work hard and run hot. This plug is designed with heat resistance and durability in mind for demanding operating conditions.

    Simple Replacement

    Replace your worn L7T-type plug without complicated modifications when dimensions and specifications match your engine. It's suitable for a range of compatible chainsaws, brush cutters, trimmers, and other small-engine equipment.

    3 Electrodes vs. Standard Spark Plug

    See why the 3-electrode L7T design is a smart replacement for compatible small engines. Multiple spark paths help support reliable ignition and longer service life, while the heat-resistant construction is built for demanding working conditions.

    Testimonials

    • My chainsaw starts right up.

      Replaced the old plug in my chainsaw and it has been working great. Installation was straightforward and the engine starts reliably. Definitely worth keeping an extra one around in the toolbox.

      Robert D.

    • Simple replacement that does the job.

      My old plug was getting pretty worn, so I decided to try this one. It fit my compatible small engine without any trouble and has been running well so far. Good inexpensive maintenance item.

      Michael R.

    • Great for my brush cutter.

      Installed it in my brush cutter after having some starting issues. The fit was right for my machine and it fired up without a problem. I've used it several times since and everything has been running smoothly.

      ❓ Frequently Asked Questions

      What equipment does this spark plug fit?

      It's designed for compatible 2-stroke gasoline equipment that specifies an L7T-type spark plug, including certain chainsaws, brush cutters, trimmers, hedge trimmers, and blowers.

      How do I know if it fits my engine?

      Check the model printed on your current spark plug and compare its dimensions. This version uses an M14 × 1.25 thread with approximately 9.5 mm thread reach. Do not buy based only on the appearance of the plug or engine size.

      What's the advantage of three electrodes?

      The three side electrodes provide multiple potential spark paths, rather than relying on only one side electrode. The product documentation positions this design around improved ignition reliability and extended service life.

      Is it difficult to install?

      No special modification should be necessary when replacing a compatible plug. Allow the engine to cool, remove the old plug with the appropriate spark-plug tool, and carefully hand-thread the replacement first to avoid damaging the cylinder-head threads.

      Will this automatically make my engine more powerful?

      No. A spark plug cannot fix unrelated engine problems. Replacing a worn or fouled plug can help restore proper ignition, but starting or performance problems can also come from the carburetor, ignition coil, fuel, compression, or other components.
