Ok I got it all opened up and found the "L" on the crank. Should I replace all the bearings in the engine? It looks like there are about 3 sets? Also, should I wipe down every internal part of the engine while I have it apart? If so, how should I re-oil them, just put nitro fuel on it or grease if it's a bearing or shaft? I noticed when I spun the fly-cone it wasn't spinning the prop. I made sure the crank pin was in the correct place. I think I might have unscrewed the drive shaft by spinning the prop or the fly-cone the wrong way, is that possible? Anyway, it works now, so I think I screwed it back in. So there doesn't seem to be anything wrong with the flex shaft or the drive shift.
Thanks a lot Mark, I appreciate it!
