I flew a Comanche 260B for years. It had an alternate air door that was held shut by a magnet of the type used on kitchen cabinet doors. Has anyone used this on an rv7 with an IO360? It was very simple and worked when it needed to. I had 2 times that I got iced over and the door opened. You lost a good bit of power until the engine had enough suction to pull the door loose from the magnet.
