Bob,

The biggest mistake you did on your CIS was tinkering the fuel mixture setting without verifying the absence for source/s of unmetered air. SOOK’s procedure for adjusting the fuel mixture is good except he failed to mention to verify the absence of unmetered air. I called his attention about this matter and he could not edit the posts due to the time frame. After a certain time, the posts become locked.

Anyway, no amount of adjustments will correct your problem if you have sources of unmetered air. The best you could achieve is to make it more RICHER to compensate. At this point, we are not even sure you have unmetered air going into the system. But we don’t know that as fact.

You are hoping it is free from any significant sources of unmetered air. You could be lucky and all is good. But you can not rely on LUCK for diagnostic testing. Maybe you could not find the leak but that does not mean you don’t have an air leak. Test and verify.
