All good points above. I am a licensed pilot too and have worked on many different engines with carburetors and/or fuel injection for years. We are a little off topic, but the purpose for running an engine rich at high power settings (like on take off in an airplane or at maximum load in a generator) is to reduce cylinder head, exhaust valve, and exhaust gas temperatures. It also cools the intake charge when the excess fuel evaporates (but does not burn because of lack of oxygen) reducing the possibility for detonation. It can eventually foul spark plugs, build combustion chamber deposits, and, dilute the engine oil with fuel if done too often and for too long. It also slightly slows the flame speed in the combustion chamber.
To be clear to the originals posters question, yes, you could tune most generators to operate at altitude, but, don't expect them to perform at the specifications the manufacturers publish for operation at sea level and standard conditions. (29.92 inches Hg, 59 degrees F, and low humidity)
