You'll be rich at 5000ft. Everything should be jetted down a little: main, needle position and mix screw.

haha, that's so cool. I never thought of that. Il hafta try to see if i can find a difference tomorow. I keep mine at 358 feet above sea level. Then my yards twisty so it goes from 400 to 300 feet above sea level. Then at my friends house that i usually go to it's all from -200 to 1500 above sea level there.
