Please trim replies?

That doesn't make sense.  Richer burns cooler, plus
there are not enough oxygen atoms to completely
combust the fuel in any given area.  Less fuel burning
+ fuel burning at lower temp = slower burn rate (on
both counts), if basic physics is correct.  Cooler
temps mean fewer actual molecular breaks and
reformations, as there's less energy available to do
the breaking; fewer oxygen atoms mean that some
fraction of the energy used in breaking apart the
hydrocarbon chains never gets "returned-and-then-some"
from oxidization.
