There's an AD that applies ONLY to the O-200 and ONLY if it is equipped with Gen-u-whine Continental cylinders. It does NOT apply to C85 or C90 or any other continental engines!!! It had to do with head-barrel separation. The rocker shaft boss AD is different, applies to all C-series and does not affect the timing. Use the timing specs on your data plate, or if not there, from the overhaul manual. C-85 is 30/28 and C90 is 28/26.
