Could be. On the other hand it was a relatively cool day, especially on top of the passes it was down right cold. We were all pretty much using the same type of fuel, why then did many of the mechnically pumped, carbbed vehicles never skip a beat?

Several of the "vapor lock" issues I saw appeared to actually be engines loading up from being too rich. That could be due to a carb needing rebuilt, floats too high, sea level jets at high elevation, ignition timing not set for high elevation, etc. All of those things are amplified at elevation and we were running between 11,000 and 12,600 most of the day.
