Ed, lookat Ercoupe Memorandum No. 66 where it discusses the maintenance to the automatic carb heat on"early Ercoupes", This appears to say that the automatic throttle/carb heat was dicontinued at some point in the production of Ercoupes.The Ercoupe parts manual does list parts for this assembly, but the Forney, Alon, and Mooney parts and service manuals do not make any further mention of the automatic functio but does show manual carb heat operation Is it possible that this faeture was discontinued when production re-started with serial number 113 after the war??? Regars, Tom

To: "ety" <[email protected]> Date: Thursday, February 19, 2009, 6:06 AM Bill, thanks again, you are a great reference. So, the incident is recounted in the book. (I’m sure I read it when I read the book but the details about the carb heat aren’t as I remember. I __vaguely__ remember Fred telling us this story at a flyin. I’m not sure. In “From the Ground, Up The Autobiography of an Aeronautical Engineer,” Page 186-187 Fred wrote, “We did not know nearly as much about carburetor icing then as we do now. I had thought that rather than put the complication of an extra carburetor heater on the airplane I would simply draw off the carburetor air from a warm place inside the engine compartment and let that do the heating job of the carburetor, even if it cost us a slight amount of power. Obviously, that turned out to be an oversimplification. In this case, the long oil warm-up run was just the wrong thing to do – for it in fact had set up the carburetor icing.” OK, that still leaves open the question was/is there an “automatic carb heat” on some Coupes? If it does exist, should it be there? Ed From: ercoupe-tech@ yahoogroups. com [mailto:ercoupe- t...@yahoogroups .com] On Behalf Of William R.

Fred relates it starting on page 186 of the "From the Ground UP" autobiography. That part you got right ;<) You're most welcome. WRB
