Gary, just stick with your carb. True that you lose some power at high elevations, but so what? You still have plenty to get up the hill and realistically, how much time are you going to be spending at high elevations? I just bite the bullet with my Webers and wait until I get lower. If I was to stay at a higher elevation more than a few days, I would easily change out my main jets, as you could. My 3 1/2¢
