Have you filled up with Albuquerque gasoline yet? I'm pretty sure that
high-altitude places sell you high-altitude gasoline. Maybe that's just a
nasty rumor... I would do a few perfunctory checks before twiddling the
carbs too. Make sure the air cleaners are nice and clean, etc.

Yep, sounds OK to my mind. Also the gasoline may not vaporise as well at
high altitude. Are you running SUs? Do the "lift the piston" thing and
see what your car is telling you.
