O2 Sensor on a Carb Engine Question

If there is a cylinder misfiring or incomplete fuel burn it will show as lean on the gauge since not all the O2 is being consumed by the engine and is just passing through. So yes if the engine is running so rich that it can't properly combust the air/fuel mix the sensor will show a false lean reading.

I was wondering if anyone was going to mention that. :D
This was the statement I remembered and needed reconfirmation of. I am hoping for dyno data to prove the case. It would maybe take an O2 in a header head pipe for a cylinder and force the cylinder to run very fat and see. Like increase the duty cycle of just 1 injector. Read how that cylinder reacts and total exhaust also. Or a cylinder drop test to turn Ignition off on a single cylinder. I wonder of I could get this data at work....
