Looks like the trim slots are candidates for exhaust?

Do a quick explanation sketch Bud.

Played with this a bit more today by adding an additional belly vent aft of the curtis valves; then another pair of vents just below the leading edge of the Hstab; then added a passage through the D panel.

The top mounted exit vent provides the most volume flow through the entry vents into the cabin. However eliminating both top and belly exit vents and retaining the D panel port and rear exit vents provides a more uniform flow and less disturbance to exterior free stream air upon exit.

The model being tested has the flap bar slots blocked off; there would normally be air exiting or entering from this area; which is possibly where CO is getting in from prop swirl turbulence.
