It was a problem getting the ring in because the bottom of the bore flares out.  You can't use a ring compressor.  I put the top of the piston in the bore then tried pushing the ring in with the tip of a pick.  In the process the ring broke.   What's the way to do it?

Where should the ring gap go?  Is it centered on the longest section of uninterrupted wall?

The crank weight has 11 degrees stamped on it.  How is the timing set?  I have not taken off the flywheel and assume it only goes in one way but not sure.  There is no key shown on the exploded view.
