My new C-150/150 taildragger has a Lycoming O-320 E2A and a Sensenich 74DM6S5 prop. The guy I bought this airplane from rebuilt it from a wreck, and I don't have as much of the paperwork as I'd like for all the mod's done to it. I've heard of some engine/prop combinations that have rpm limitations or more accurately prohibitions, usually in the 2000-2300 rpm range, due to harmonic vibration problems. Does anyone know if there is such a limitation on this engine/prop combo, and/or where I would find information on this issue?
