Where should my CO be set to???
 

I have a 77 930 with a 3.2 Motor. K-27/7200 and full bay IC.

Can anyone tell me what a safe CO number would be. I think I am running way too fat by the color of my exhaust tips and the smell anyway. So I plan on putting it on the 5 gas today to find out and adjust it as needed.

Thanks in advance!

0.6-1.0 CO% Measured ahead of the cat. conv. and with the oxygen sensor plug disconnected. ( Spec Book )

Wherever it idles smoothest without the HCs starting to creep up. Probably arouind 2.5 to 3.5%.

Thanks guys!!!

Checked it just a few minutes ago. It is at 2.5 on the nose at idle. At 2500 it climbs slightly to 2.85

I think this will work. Nice! For a change I dont have to mess with something? (LOL)
