To further satisfy my curiosity I completely disassembled the FS-48 that has the most runtime on it on etherless fuel. The engine was purchased used and I didn't inspect it prior to conversion. The crosshatch on the bushings in the conrod is like new. There is no indication of wear here. I was expecting some wear on the top end but if I had to say that there is wear it's at the big end on edge of the bushing. There is some light scuffing. The sleeve is in great shape considering it was missing one of the plastic bushings on the piston pin at one time. The piston pin ended up scoring the liner, and I discovered it when I had it apart for inspection previously and replaced the plastic bushing. I continued to run it as it was. The liner outside of this scored area looks great, like would be expected of any low time engine. The intake lifter has some wear but I don't know if this was there when I received the engine.
