I know it has knock sensors, but I don't know about an engine speed sensor.
Seems like there is a Hall effect sensor, but I don't know if that is
involved in timing or not.
I didn't think that the timing was adjustable at the distributor, but
according to Tony J it is adjustable at the distributor, if you defeat the
tamper shield. Haven't looked at it yet to see, though.
