Thought I should start a separate thread for this engine. This was a Thermo King refer unit that I pulled out of a box van body and figured I should try to salvage the engine.
I hope so. I'm surprised how good it looks inside after sitting out for around 40 yrs.That right there is gonna be a runner!
I see the retainer clips for a cap on the distributor so it must have had one at some point. I still need to remove the coil from the refer unit frame and see if it is any good. I need to look on my old computer to see if I have a PDF manual for these engines. Not sure how you set the timing with this distributor setup. I want to remove it and clean it up in the bead blast cabinet and get some new points in it. I don't see a condenser in there so are they mounted externally somewhere?Its cleaning up nicely cjet I to think it will runwith a little work the distributor just may work
If I had to guess, it was hooked up to a thermostat and when the temp rose to above the setting it pulled the governor open and then the unit would start cooling down the box. Look and see if there is some kind of clutch on the compressor or output of the engine. I'm thinking it would have been on the engine and probably a centrifugal clutch.Not sure what this part is. Looks like a solenoid the pulls on the governor linkage.
It does have a centifugal cluth on the engine.If I had to guess, it was hooked up to a thermostat and when the temp rose to above the setting it pulled the governor open and then the unit would start cooling down the box.

I'm sure you are correct on it running continuously but coming down to idle once the temp was down. Just like our gas-powered miller arc welder that idles until you strike an arc.The reason I I suggested throttle is because if the engine runs continuously the controls for maintaining the temperature would be much simpler. I spent many years working with industrial refrigeration systems but like Doug I never had my hands on one of these. We used to load refrigerated box cars and I remember they had to be started before they brought them out to the plant. Can’t remember if they stayed running while they were loaded.
I’d have to see the controls or a schematic to know for sure.
