Here is a mechanical tachometer

I've had one for close to 30 years. They work great. You can use it on any engine or even electrical motors.
You turn the dial and the wire extends. When the colored end tip matches the frequency it will be a blur. You then read the RPMs or frequency.
You should be able to pick one up at a lawnmower repair shop.
Of all the tools I picked up after numerous years of being a mechanic I still think this is the coolest.
