If you need data of valve clearance gap of the diesel generator, you can check on the operation and maintenance manual. If still can not find, try to ask your supplier whom supplies the diesel generator to you.
If you need to have a generator set in future, please refer to www.dieselgeneratortech.com.
SOURCE: tappet clearance and spark plug gap on 5.5 hp ohv
I have a Robin but they all are pretty much the same for plug gap and tappets. I worked in a lawnmower small engine repair shop for many years in San Diego
I set them all the same and never had one return. I just did mine a couple of months ago and hand lapped the intake and exhaust valve seats. Starts first time everytime like the 7.5 year old unit is new!!!
Plug gap 0.19
Tappets
Intake .005 cold
Exhaust .006 cold.

Start looking at your safety circuits.
1. High water temp
2. Low Oil
3. Low water etc...
From the manual these are the protection circuits.
• Engine protection: low oil pressure, high engine temperature.
• Genset protection: under/over voltage, overload, battery charger failure, battery voltage out of limits,
under/over frequency, start failure.
• Circuit breaker protection: IV poles.
• Differential protection.
Any one of them will trip the fuel relay closed. What you may be able to do is disconnect one at a time each protection circuit and see when the fuel relay opens. (Make sure to reconnect each one if it had no effect on the fuel solenoid)
Once you isolate which circuit it is in then you can chase wires or change the bad switch.
