This weekend I want to see what the clicking is. Flipping the prop thru compression last night yielded something strange. When it is clicking, there is little to no compression. If I turn it backwards a few turns slowly, then turn in the direction it now runs, it becomes quiet and the compression returns. Really odd behavior. I am at a loss to explain it but maybe after I open it up, I'll see something wrong. When I changed the ring, the piston looked practically like new, but it had next to no compression so I changed the ring. I have another good case with good crank and quiet bearings but a scored cylinder and piston. Might try transferring my good parts to that one in the odd chance I'll end up with a perfect engine.

Is it possible that the crank pin for the rod has loosened, causing the click I am hearing? If that is the problem, that crankshaft is not useable. Maybe I should just take it apart and see what's going on.
