Taking my dual weber 2056from it's home at sea level over ebbets pass (8700 ft)next week. Doing a valve adjust before, and general check, but is there anything specific I should do? Think I will need to fiddle with the idle mixtures urging the drive?

Any honks are welcome.

(Oakland, eh? (IMG:style_emoticons/default/idea.gif))

I'm wondering about this too, since I'm thinking about driving out to Red Rocks. "Don't stop" isn't gonna work as advice for a multi-day trip... Anybody care to speak to why altitude is a problem, and what you can do about it?

I'm guessing that high enough altitude means enough of a drop in atmospheric density that the air/fuel charge is off and the car runs too rich. There are mixture adjustment screws we'd want to find, mark the position for home, then at a certain altitude lean it out a bit, counting the turns? (IMG:style_emoticons/default/confused24.gif)
