I haven't followed the entire conversation completely so excuse me if 
this has already been brought up.

Would you not consider a stoich mixture of fuel one that consumes all 
the available oxygen? If oxygen were rendered from the combustion event 
then I would expect there to be sufficient fuel to combust that as part 
of the equation.
