Happy New Year everyone! I have a strange occurance that you listers might know the cause of.
When I pull the power back for high speed descent I get exhaust smell in the cabin. It goes away if I add power. My exhaust pipes are cut horizontal and flush with the bottom surface of the cooling air exit (out of the slipstream). I'm guessing that under power the jet of exhaust clears the fuselage, but not when powered back.
This happens with the cabin heat and vents closed so I don't think those are the culprits. My canopy and firewall are sealed well. Anybody have this problem and a solution?
The next place for me to look is the flap rod holes in the fuse. Any ideas or photos on how anyone has sealed these up?
Reply off list if you want. Thanks for your help,
