A65 actually. What a great little engine. I fly in the mountains of western Virginia (USA) and it's been completely reliable. I'm religious about carb heat, though.
I'm a glider instructor and glider tow pilot, and fly a Pietenpol Air Camper that I built from plans. I owned a Bellanca 260 in a partnership but we just sold it.
