Depends on the model of Onan. Some have an adjustment screw you turn in. Some adjust with a nut on a threaded shaft that pulls on a spring. Some have an electronic governor control. That you adjust with a small screw driver
As for as I know Onan never published that information. If it is a non Onan engine. You will have to check with the engine manufacturer.
One can find parts for an onan engine online. Some of the useful websites are Onan Parts, Discount Online Parts, Cummins Onan and Jacks Small Engines.
need a wiring diagram for a sears ss16 tractor with onan engine
Depends on what the equipment you have.
What is the reported manufacturers weight of the ONAN 250 HD GEN SET electrical generator?
Depends on the engine.
Onan no longer makes engines. But with the older ones it is hard to say. Both had very good engines. Some better than others. I would say Kohler had the better single cylinder engine after Onan stopped making the LK. Onan had better RV generator engines. On the larger units they were both the same in quality and support.
Depends on what fuel you are burning
Should be 110 PSI
That engine holds 1.75 quarts with filter change.
The FRAM PH3614 is the oil fiter that cross references with the Onan 122-088 that was installed in the unit. It is half as long as the Onan 122-0800 that is recommended by Onan and actually removed from the engine for replacement. The way the engine cowling is bullt, that means that the oil filter cannot be screwed in or removed because it wsill set too deep in the cavity to get fingers or an oil filter wrench into it.
