It takes Model and Spec Codes plus a Manual to adequately troubleshoot. I know that for the 4KY, a slightly larger genset built along the same concept as the 28 series, the Oil Switch was discontinued after a certain Spec Code. People with later Spec gensets spend a lot of time looking for a device that's not there.
Just for what it's worth, we had a gummed carb on our 4KY. I could start it, and it would carry a load until the load dropped off. For example, I could start it, turn the A/C on Max Cold, and it'd run that A/C for hours. You could hang meat or ship flowers in that coach. As soon as I reduced the thermostat setting so the compressor dropped out and the load became only the fan, genset would quit and not want to run again till it had cooled.
