EGO and the Smog Pump

[Robert Harris]

Dah, correct me if I am wrong ( aw go ahead and do it anyway)
but doesn't the EGO sense total oxygen in the exhaust stream
and get "happy" around stoic?   If true, then when we shove 
extra oxygen via the smog pump into the exhaust, do we not have
to shove unburned fuel from a too too rich mixture into the exhaust
to make shore that the result is stoic at the sensor?  Am I missing
something here or is the total extra oxygen so low that it doesn't
make much difference in the fuel consumed??


If the first ingredient ain't Habanero, then the rest don't matter.
