Running your generator at higher altitudes with the sea level jetting will cause it to run rich. It may smoke a little, maybe not. It will use more fuel than necessary and it may foul the spark plug and/or dilute the engine oil with fuel. Running it at sea level with the high altitude jet will cause it to run lean. You may experience loss of power, hard starting/rough running, or excessive engine temps.
Time will tell how it effects longevity. Your choice.

I always thought it was just the opposite. Higher the altitude, thinner the air, fatter the jet orfice to compensate foe the thinner air.
Ummmm. You always thought wrong.
Thinner air means less oxygen. You need to reduce the gas flow (smaller orfice/jet) to keep the air/fuel ratio the same as it is at sea level.
