Priming like that makes more sense. While my dealer told me to prime until the lamp came on each time I started it, it made no sense to me that you would have to prime any carb unless it sat for weeks (or ran out of fuel).
I did check my elevation knob and it was at 0. However the first increment up from there (about 1/8 turn is labeled 3250 ft.) So I tried to set it for about 1K feet with 1/20th turn?
Tried starting with the gen cold and warm. No difference. Takes about 3 or 4 restarts at 3 or 4 sec each before it will continue to run. (However I have no surging and great regulation when it does start. That is why I am not complaining to the dealer. After they work on it, it will probably start and that is all.

Fixed my issue, that is why I posted. Obviously the Onan manuals must be RV specific, as I have heard every prime combination possible on this thread.
