Depends on the engine.
What is the reported manufacturers weight of the ONAN 250 HD GEN SET electrical generator?
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.
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.
Many ONAN Generator Engines.
Arzum Onan is 178 cm.
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.
