The carb adjustment is easy.  Get the gen started, warmed up and put about a half load on it.  Start screwing the carb bottom bowl screw slowly in until the unit starts to labor, then reverse rotation on the screw 1/4 turn.  If you go into altitude, you're going to have to readjust it everytime.  I know this since I had a 6.5 Onan Commercial on my big rig-it was a pain in the you know what.  Now with my Diesel genset in my bus, I do zero to it.  In fact in 1200 hours of use (like 48,000miles), the only thing I've done is oil change and filters-can't beat the reliability of Diesel. Good Luck, TomC
