JRV: Interesting thread!
Are you adjusting the vacuum first, then doing the CO reading? If so, do you find that you have to re-adjust the vacuum?........and vica versa?
I notice that you are using the exhaust gas taps, to check the CO........I recall there are 2 on each side, each serving 3 cylinders. When I pulled the engine, several of my taps where either broken, or cracked, at the pre-cat, where they insert into. By the readings, yours where obviously intact. Are you testing BOTH ports on each side?
It appears that the car has a standard exhaust. I assume that you used the ports (as opposed to the rear muffler tips), because of mixing, in the exhaust, of the gases........hence, not accurate readings. If one had a Tubi, then one could test from the rear muffler tips.......right?
