Russ,

You may have an injector that is not spraying cleanly. The first thing I would do is put the generator under load to get it hot. We hardly ever run them near capacity, and diesels don't like to idle. Before I removed injectors, I would turn all the AC's down as low as they will go and run them off the genny. The idea is to get some load on the engine and burn off any crud on the injector tips.

I am assuming you have checked the air filter and it's clean.

Also look around the little turbo on the exhaust to make sure you aren't losing turbo boost.

I posted earlier about how much better mine ran after removing and cleaning the injectors in addition to adjusting the valves. It was not a difficult job at all. The hardest part is disconnecting the slide from the pneumatic cylinder so you can get easy access to the motor. That would be my next step if the blowing out the soot approach didn't cure it.
