I have been chasing higher than normal CO levels on my aircraft, hence the research into airflows from the engine compartment. I have been looking at bellows around the pitch tube behind the baggage bay to close off the airflow through the flap slots and forward through the tunnel. I am ,however, struggling to understand why I should have a problem on my aircraft when others are not reporting problems. The trouble with measuring CO with a digital sensor is that once you know the reading you feel you should do something about it, even if it is within limits. I am getting 11 - 20 ppm in cruise and up to 35ppm on approach with the flaps down, with a normal limit of 50ppm for GA aircraft but zero would be better!

Hi Brian, So true^^! Also the higher the number of parameters measured, the higher the amount of head scratching...
