I had another look at the solenoid mechanism today and Bronco is correct, it is a shutdown only solenoid. One would crank the engine with compression released (the tripped mode of the solenoid) then mash the curved handle down to cock the solenoid and allow the compression release pin to retract. When its time for shutdown, a push of a button, mounted remotely, would fire the solenoid which trips the latch and the springs force the compression release pin back under the collar on the lifter. It makes sense as one would check the oil and such when starting the engine in the generator house, but could shut it down before bed, without a trip back to the generator shed. So it is the same thing as the old shutdown string system used throughout the Bahamas in the old days.
The mechanism is spring loaded so when you push down to get compression after cranking it over, it automatically latches itself in the "run" position. A very simple and sturdy system. It could easily be adapted to work as a safety shutdown for low oil pressure or high temps. Regardless, it is the only one of this type I have ever seen here, and there were a lot of Listers around here years ago!
