I was looking in a new Cessna that is fuel injected, and I was looking for "carb heat", then I realized it was injected and assumed that it didn't need it. So here I am, looking at the panel, and I see a red nob that says, "Alt Static Air Pull On". Is that what you are referring to? So, would that then pull intake air from inside the cowling instead of the outside? So, here's my point: I am thinking about developing a home made injection system for my motor. The throttle bodies will be located on the top of the engine. My air would be pulled from an air duct in the cowling, and since most of my flying would be in Florida, and it does get very humid sometime on cold days, icing would be a concern, I would think. SO, that being said, would I need to have carb heat pulled from the manifold, or would "alt static air" from inside the cowling suffice? Your opinion? Scott __________________________________ Yahoo!
