Works great on small engines

Hooked it up to test a Honda GX340. Worked great, goes on easy, and let's you see that it's getting spark while allowing it to start and run so you can verify spark is good while it's running. I could see the spark light just fine during the day. While I wouldn't body slam it on concrete it seems to be sturdy if you treat it like the electronic tester it is.

Good product

Very bright and works great. The shape allows it to fit into tight spots on a lawnmower and also for general automotive use as well. Would recommend

Maybe the BEST spark tester!

Well made. Nice to be able to change the configuration from straight connector to right angle connector. The extra length of the silicon coated wire is useful. The light can easily be seen even when using the ignition coil of a small pull start engine.

Great little tester, especially with a few mods

This is a nice quality item for sure. The boots on each side are good quality rubber and everything snaps together really nice.On my particular tester (see attached photos), I made a few modifications which make this particular tester extra versatile. You can see I have taken a sharp razor blade and cut the boot where it extends on the 90 degree part.I made this modification because I use this tester on both my chainsaws as well as my Toyota pickup and sometimes I need a little access point where i can clip on an external timing light. Sure, they do have induction type timing lights, but those can give inaccurate readings due to spark plug wire shielding and also other spark plug wires nearby. What I have done is cut the boot where it makes a 90 degree turn; this allows me to either use the tester with or without that little section of rubber. When used with the cut off piece installed, then it works like normal. When used without the small length of rubber, then I have a nice clean metal contact point for either a direct electrical clamp or even the induction clamp (away from other spark plug wires). This little upgrade is really nice, just don't grab it with your bare fingers while the motor is running :)You can also see in the photos that I have replaced the light with a length of just plain spring. This allows for a more solid path, which can sometimes help improve idle. Nothing wrong with the original light that is supplied, but when using high voltage coils on race motors, etc. sometimes I just like having a direct path to the spark plug also. It's easy enough to unscrew the plastic housing and return the original light back into the mix also, thanks to the very nice design by Lisle.Great little addition to any tool kit. 5-stars for sure.
