AFR's (Idle and Cruise)

I know there is a similar thread, but I did not want to hijack....

Regarding running O2 Disconnected, Cruise AFR's low 13's.

My Warm and Cold pressures (Leask WUR) are spot on spec (lower end, but in spec). I have adjusted my AFR's at idle from 12 - 13.5, and my steady cruise AFR's are still rich, at low 13's. The cruise AFR's are NOT effected by changing the CO at idle, as I have been experimenting with this. My car idles much better at 12.5 than 13. 5, so I have it set at 12.5. Cruise AFR's are still low 13's. I do have a freq valve, and running O2 disconnected.

My vacuum advance and retard both work on the dist.
