67 twin turbo dart

It’s worth a shot. From what I’ve learned, that sensor has a small strip of the face (as opposed to the entire face) that is actually the sensor. Given your thin reluctor wheel and the little strip of sensor it’s easy to see how it could lose signal. I have a 36-1 wheel just like yours and I opted to not use it and went to the wide face AR Engineering wheel.

My setup. No problems once I got the pull up resistor in it and also took care of the broken weld holding the wheel on the pulley.
