The Tiny Tach has a wire that you wrap around the outside of one spark plug wire to sense RPM. There are others out there that have a sensor that clips around the outside of a spark plug wire – all are easy to use. A tach is the best way, but I don’t generally use one – I’ve gotten a bit of a "feel" for proper performance and engine sound. You can buy a TinyTach online at E-BAy , Amazon, and other places. for $45 to $50. They are also good for setting idle RPM, and can be used on virtually any gasoline engine. You just have to, as was said in the previous post, set a tach up for 2 or 4 stroke and the number of cylinders to get a correct reading.
