Engine with Cylinder Temperatur Thermocouple and rpm sensor. The cylinder temp sensor is made from an electrical eyelet. The MAC 67 water jacket had to have a notch machined in it to allow for a glow plug driver to clear the thermocouple.
The rpm sensor uses two magnets 180 degrees apart in the flywheel. I made a bracket to hold the sensor out of aluminum. It mounts to the engine rail. This arrangement keeps it clear of the starting belt.
