Dave Karren writes: "I use a 65 Continental carb under the engine using a Y updraft running to each bank made out of exhaust pipe. It works good. It keeps the velocity up. I tried larger, and I may have gotten more power on warmer days."
"164 engine is all that will work up here at this altitude. Cams and loads have a lot to do with it also."
"I use the blower, and hand starting."
Dave Karren first flew on Corvair power in 1968. Pictured below is Corvair-powered Pietenpol Scout N4991 that Dave built, flew, then sold about 1970.
