How do you replace pull rope on snapper s31sngbc?

To replace the pull rope on a Snapper S31SNGBC, first, remove the recoil starter cover by unscrewing the screws holding it in place. Once the cover is off, take out the old rope and the spool, then thread the new rope through the hole in the spool and tie a knot. Wind the new rope around the spool in the correct direction, reinsert the spool into the recoil assembly, and reattach the cover. Finally, ensure the rope extends and retracts smoothly before testing the starter.
