My generator is a dog to start and it backfires a few times before starting when it is below freezing. Once it goes it works OK. I tried installing a primer ball on it and it didn't help so it needs a resurrection.
So, is it better to rebuild the carb or just replace it? Both options are available on ebay for about the same cost.
ONAN Model 2.8KVFA26100K Spec K, S/N A040592835
Onan no longer sells any parts for the carburetor. I think some stuff is available on Ebay as are cheap replacement carbs. You would probably be better served to keep up with the Sea Foam treatment and maybe adjust the choke per the manual.
Probably not your problem but I had trouble starting in the cold. Turned out to be slightly low oil level. Added a few ounces and all was well. Check your oil level when cold.
Contrary to your video your Onan does have an electric fuel pump. They often need replacement. It has a fuel filter, too.
Don’t hold the start button down so long. Dunno why but it won’t start that way. Pause, hit the button, and away it goes. I expect it has something to do with voltage, electric fuel pump, and starter voltage drop.
