I've been asked about my RPM indications for these little guys. So, to clear that up, I use a laser tachometer reading a patch of reflective tape stuck to the flywheel. On some highly reflective flywheels, I have to switch the tach to contact operation and press a rubber cup ended shaft to the end of the engine mainshaft.
