I recently got my PA-12 floatplane flying after a 5.5 year rebuild. It has an o320 150hp with pa-18 exhaust. Very impressed with performance and it flys great.
The only issue I’m having is it’s getting exhaust in the cabin from outside. I’m guessing due to the low pressure in cabin. I’ve sealed up the door, plugged off the cabin heat and tried extending the tail pipe 4”. None of this has helped.
The only thing left I can think of is somehow sealing off the front gear fitting area and plugging the drains under the fuselage. The wing root fairings are not completely sealed but I don’t see how it would get through there.
Anyone else have an issue similar to this?
