Great product and long plug to go down in the cylinder to connect to the spark plug and great to put onto the coils, long enough to see from cyclinder 1 and 8

Why did I wait so long to buy one of these?
This device saves so much time trying to determine if a small engine has spark. It is so much easier than pulling the spark plug and trying to prop it up against the case of the engine to see if it has spark. Just hook this up inline to the spark plug, crank the engine, and get immediate feedback that spark is present. This is great.
