Using the backplate sensor, as I spin the crankshaft by hand slowly, the sensor light on the receiver flashes twice as the rod goes by. I assume its sensing one side of the standoff on the crank for the rod, then the hollow in the middle of the standoff and then the other side. Is this what others are seeing? I would guess that when the engine is running at speed it goes by quickly enough it only registers once each revolution?
