When signing up with the FAA to get online, electronic notification of A.D.s,etc., under the new system, one needs to state engine type more specifically than just "C-85." There seem to be different suffixes, e.g. "C-85-12," etc. I only know the engine in my 415-C Ercoupe is a C-85; can anyone please tell me how to determine what suffix applies? If there's any sort of placard, where should I look for it? Thanks --
