The starter works beautifully, so do glow plugs.
There is a white OVERSPEED button on the engine, whose purpose is
unclear to me.
The engine would start any time I would depress the OVERSPEED
button. It runs for as long as I press the button, producing menacing
diesely sounds and white smoke. As soon as I release the OVERSPEED
button, the engine stops.
My supposition is that the overspeed button is linked to the
governor/flyballs etc, and is designed to act to stop the engine if it
detects overspeeding. For some reason, I suspect, this system is not
working properly and engages when it should not engage. Maybe
something is simply stuck from decades in storage and need to be
unstuck. (like the "governor arm" or whatever.
I also suspect that it was related to the rattling noise coming from
solenoid pictured here:
This rattling noise occurred when I pressed the start button and at
the time when my starter was not actuating. (it cannot be heard when
the starter actuates because the starter is louder)
Any thoughts? This does not sound normal and I would not let my engine
run for more than 15-20 seconds. Not even enough time to test the
genset with a voltmeter and a kill-a-watt.
