I’m pretty sure the carbon seal was installed the proper way except the quad seal was placed between it and the springs cup washer. The carbon halves were kind of cockeyed when I split the cases so the one half must have been rubbing on the lower bearing. You can see the wear pattern in the one half. This might explain why the bottom piston was scuffed a bit to. The lower cylinder was probably running lean or else water made its way in to wash the fuel mix off the piston.
