1992 big boss 6×6 starter help

We have a 1992 big boss 6×6. Recoil starter string broke and trying to fix. Having rough time getting to recoil spring? Any ideas? I have cover off but cannot dissemble the recoil unit and the plastic piece that the cord is wrapped around. second issue is the electric starter. Do I need a gear puller to remove flywheel? Help please…
