Sir,
that was the second time I flew with the CO detector. I don't know if it works or not. I can tell you that as I was on the ground for about 10 minutes waiting on our take off, I could see the numbers increase from 0 to 4. I opened all my vents and the number went back to Zero. I hope it works better than the piece of paper that changes colors.
Regarding the location. I don't know that area at all. I was at the intersection of "Aileron Hinge to Spinner Line" and "Little Opposite Elevator Behind The Rudder".
