After disassembling and cleaning the engine, some of the main problems Bill found were a broken timing chain, armature with excessive wear, excessive crankshaft run out, worn exhaust guide, and probably a few other things I'm forgetting. In addition to replacing those items, all bearings, seals, piston rings, hoses, and gaskets were replaced. All of the photos in this post were taken by Bill Rogers during his rebuild of my engine.
