I'm thinking more of the fact that it takes a lot of extra fuel to make
an infernal combustion engine run properly when it is cold, as in very
cold, as Zsolt said, -40 cold... or at least, say 0 degrees F.  if the
open loop enrichment you speak of has that range covered, I stand
corrected.

I still think the lack of feedback control on the idle speed is an
oversight that should be corrected.
