Broken starter cord on briggs and stratton quantum 40 roughly 1994 how to repair

Remove the recoil. Sometimes depending up on model this required complete air shroud removal. Remove the parts of the old rope. Remove the rope fro the rope handle. NOTE the knot in the handle. Brun both ends of the nylon rope with a match and pinch the burned end into as small of circumference as possible. Install new rope into the starter handle and tie the knot. Pull the new rope into the handle until it seats securely.

Prewind the recoil pulley as far as you can easily wind it. Back it off (unwind) just until the rope guide and pulley knot hole are aligned. Then either c-clamp it in place with the rope knot hole aligned with the rope guide hole or have a 2nd person hold it the pretensioned spring and pulley in position. Thread the rope through the rope guide and on into the pulley knot hole. (takes some effort to get it aligned and through the knot hole!) Pull the new rope through the knot hole and tie 1 knot. Pull starter rope and fit knot into pulley knot hole. Release pulley C-clamp or have helper let go of pulley. Rope should rewind into the recoil.

Reinstall recoil / air shroud. Happy mowing!
