While doing the emissions inspection on my '76 (2.0 GC) I noticed the mixture was very rich, fluctuating between 3.5-4% CO at idle, I believe it should be about 2.5%. Which way do I turn the ECU knob to lean it out? I thought it was counterclockwise - but it's already as far as it can go... (unless I am wrong and the CO is actually OK, which I doubt) (IMG:style_emoticons/default/huh.gif)

Yep its rich. CCW should lean it out, but you've already pegged that full lean. Maybe check the other sensors...TS1, TS2, TPS calibration, consider futzing with the TS2 resistance. Should be 2.0% +/- 1..0% Is your catalytic converter still good or do you run one? See the emissions labels for both CA cars and 49-state cars below:
