Good Evening. A couple months ago I bought a used OS .40 FX I found on the Net, and installed it in my Tower Kaos. It ran fine the first month or so I have been flying the plane...until this afternoon! I couldn't even get the engine started for my first flight. When I cranked the prop, it took several tries to get running, and when it finally did fire, the engine ran for a second or so, then abruptly stopped. I heard a sharp metallic noise when the engine stopped, and it seemed as if the crankshaft froze on the spot. I removed the glow plug, and eventually got the shaft cranking again, but it didn't feel smooth; I felt a bind just before the piston got to the top of the engine. I haven't yet had a chance to remove the engine and disassemble it to inspect the inside. I don't know how old the engine is, but I would imagine it's out of warranty already. Could these problems mean that either the bearings or the crankshaft are shot? I don't know if OS carries any replacement bearings. Any advice would be appreciated.
