From half throttle to full throttle, cold air is fed automatically to the engine. However a manual control is also provided...to keep hot air feeding to the carburetor at more than half throttle setting when icing conditions prevail." This was the standard setup, NOT a modification. Very few coupes still have this linkage. Also see the Ercoupe Parts Manual, p. 22, Fig. 17. Note item 17-10: "Air filter assembly - with auto. carb heat" The Arm (17-20) and Cam (17-21) appear to be part of the actuating mechanism and remain available from Univair at a nominal price. The real question, at least to me, is how "legal" are coupes that DO NOT have this installation fully functioning and lack appropriate APPROVED paperwork documenting its removal (as to insurance and FAA enforcement ramifications). Do any of you have such paperwork (or related log verbage signed off by an appropriate authority)? Review of the 415-D and 415-E & G Flight Manuals make no mention of this feature, while the Parts Manual says the parts mentioned above apply to "All". I would speculate the "auto carb heat" function was omitted from all models after the 415-C. If anyone on this list has any clear indication to the contrary, I hope they will share this with us.
