The starter rope has pulled out of the starter assembly. Process of taking the assy apart and either fixing or replacing the starter rope. Idea on a service manual to do same.

 

Take the screws out that hold the starter on top of the engine, wind the spool up until the spring stops it, back it up until the holes for the rope in the spool and its' housing line up, and feed the rope through them. Tie a knot in the end and the handle on the other end, and let it wind the new rope into itself.
