Aah - the gas / fuel mixture

No chance of any carbon monoxide there

Just from first principles (no specific knowledge):

soot implies incomplete combustion

incomplete combustion can give CO

e.g. *4CH4 + 6O2 - C + 2CO + CO2 + 8H2O

It would if it was a gas / air mixture ...

Which is why they use a CO/CO2 meter, a Telegan for example

not really come across an oxygen meter in general use for measuring
combustion efficiency

Co2 meters were used in days of yore for measuring purely carbon
fuels ie coal.
As there is much less carbon in gas, they are much less accurate which
is why oxygen analysers came in and are preferable.
