Done! Easy modification. Thanks again.

My exhaust pipe is definitely very sooty. Running rich? Or just an old pipe with years of accumulation?

The exhaust gas analysis is the best method to confirm - that will be next year's e-test for me.

Tomorrow morning's "cold" start (~15C / 50 F) will determine if the adjustment (4 clicks) will affect open loop driveability.
