 Why would you increase jet size at higher altitude?

   Mikey: 
   all of the issues you mention could contribute to the surging, but it was a hot day and having the electric fuel pump inside the engine compartment could be a major contributing factor.    
   Sounds like a vapor lock or a heat-related fuel issue, as what happened to me just two miles from home and my electric fuel pump is located up front near the tank; but is subject to all the heat radiating up from the hot asphalt pavement. The 10% ethanol in the fuels we have in the metro area does not help one bit either.   
   Most important in setting the car up for 5280' elevation is to advance the ignition timing by about 3 - 5 degrees and maybe having larger jets in the carbs (go from 49 to 51). I've been able to get by with just advancing the ignition. And always spend the extra money on the 91 octane "Premium" fuel...even if it has ethanol in it.   
   Make sure that you've replaced all the rubber fuel hoses with an ethanol-compliant hose (Gates 4219BG for instance) This is available at most auto parts stores (I've purchased it from O'Reilly's recently)   
   The PowerGlide in of itself is probably not the main culprit other than it's just a two-speed transmission, and therefore does not allow for keeping the engine rpm up a bit when going uphill (unless it's in "L" and then the rpms may be a bit too high...)   
   Hope this helps

   Interestingly, twice on my drive home while heading uphill, I had a sort of surging in the vehicle and seeming loss of power, almost like it was stalling out.  The last time it happened on Federal, I slowed down to about 30mph (not intentionally) before making it to the top of the hill.  Once past the crest, I had no more problems.  Any ideas as to what gremlin could cause this?  Would it be related to not having the carbs tuned to this elevation since bringing it from Minnesota, where my elevation was 912' asl?  Or is this more a transmission issue with the PowerGlide? 

Thanks for any help and ideas!

    My red Corsa has an Airtex solenoid style pump, the white car has a Carter vane style pump.  Both are low pressure pumps.  I think the problem with the red Corsa is the wiring in the engine bay vs the pump.  I wiggle the wires by the bulkhead connector and off it goes.  The problem has been very hard to duplicate sitting in the garage. 

   Maybe I failed to pay my dues to the gremlin union.   
   Hope this is a little helpful.

   That darn gremlin may have been passed over from Mike's car to my sedan...   the electric fuel pump decided to take a coffee break as I was waiting at the light at Orchard and Broadway on the way home. was able to get the car to a safe place and 30 minutes later, the pump was back to work...and of course that was after calling AAA for a tow and letting Karen know that I'd be a little late getting home.   
   BTW: what type of electric pump have you used on your daily drivers?   
   Great to see you and Linea today.   
   Be safe out there   JD

Good time, good people, enjoyed the cars and company. Special thanks to Mike Piper, who once again did “Corvair gremlin” duty so the rest could drive trouble-free! And thank you, Dale, for getting this up so quickly!

Hello RMCrs,

We got together for the Wilshire Memorial Picnic today.
As usual, it was a combination of pleasant weather, almost too much food, and not enough conversation.
Never seems to be enough time to catch up with everyone.

If you were unable to attend, you missed a good time and we missed you.

Check this link for a few photos from the gathering.
