Scott, the 2 opposing cylinders share lobes on the camshaft so the
camshaft may be badly worn for them. That does mean splitting the case
to replace the cam if that is the issue. New lifters as well.

I would just buy a good running used engine. There was one for sale in
San Diego a few days ago for an 85 at $350 complete.
