14.7:1 is considered stoichiometric in a vacuum with 100% oxygen to feed combustion.
real atmospheric conditions calls for 11:1 to 13:1.
he probably just read that in one of the many articles about combustion or learned it in chemistry class... it's true in the lab, but not in the real world with varying atmosphere.
