Hi Gilles,
I think leather bellows is probably the way to go. 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!
Regards
Brian

Brian,
Thank you for the information.

I would have thought that it could be easily addressed with leather bellows,
like on vintage aircraft.

This one beats me, but when there is a will there is a way...
Best regards,
