Altitude Change

I have a question for the carb gurus. The kid that is buying my waggy is planning on moving to Flagstaff after his discharge. The carb is a 2150 with compensator. Will that be sufficent for the altitude change? Runs good here at 1200 ft. but not sure how it will be at 7000ft. My son had a Edelbrock on his truck and our property is at 5800 ft. and the truck would run really bad. Would flood out and die several times before it would make the 8.5 mi trip off the highway. But the blazer with an electronic q-jet didn't even notice a differance. Just want the kid to know what to expect/do for the change. He's still out on sea duty and hasn't even got the waggy yet but his wife told me that he has already ordered a bunch of parts. His excitement about buying it makes me feel better abouit having to give it up.

Never had a problem running from sea level to up and over the Rockies passes.
Mine was a low elevation model (4,000 ft.)

Ideally you would want to lean out the jets and advance the timing. It will run, just not peak performance.

Upgrade to an Edelbrock 1406. It's leaned out 2% already. Mine runs great at 4000 ft.

If the jets & ignition timing are appropriate, it should handle that range more or less OK. Way back when I was running a carb (2150) and used to go from 1,000' to 12,000' each year, I stopped at my favorite bar at 7,000', advanced the ignition, and swapped to another 2150 I kept pre-jetted for altitude -- just quicker & less smelly than opening up the carb. The first time, when I neglected to do that, it killed the catalytic converter and the rig was making maybe 50 HP while getting about 2 MPG.
