Jerome asked how I'm measuring engine speed. I'm using a digital photo sensor, with the reflective tape on the belt. A better place/tool for this operation?
I would be curious about how the RPM reading with the reflective tape on the belt would compare to a reading with the tape directly on the vibration damper. I would place the tape maybe opposite the timing marks on the damper metal because I think there could be room for error reading the belt. The diameter of the groove on the damper and where in the groove the belt is making contact would change the speed of belt travel making it slower or faster and reading differently from the actual RPM. Any belt slippage could also affect the reading if the belt was a bit loose.
