This comment has no value, do Euro car drivers go around with a screw driver? And actually it's a 3mm allen key used to make CO adjustments.
I know this Engine inside out and I'm just trying to help the guy out. If after he dials everything in he can then decide to use or not use the stock O2 sensor. You can't expect the stock O2 closed loop to work if you have no idea what the base mixture is.
So, should we verify base mixture or NOT? CO meters are not readily available but WBO2 gauges are and they are not expensive and far better than the 80s tech CO meter.
