i have a 46 fx that has a some sort of exhust problem.
its mounted on a PA edge 540, sideways (exhust outlet facing down), with a Slimline pitts style muffler extending out of the bottom of the cowl, about 1 1/2" past the firewall.
after a flight i get quite a build up of fuel over the firewall. the bottom of the cowl gets completly covered in a thick layer of burnt fuel, and i even get a little bit of fuel in the top inside of the cowl (BTW all the fuel has been burnt and used).
can anyone suggest were this might be coming from, or is it normal[&:].
thanks
