The pull rope, also called a recoil cord, on a Murray mower can break at any location after a few years. The cord weakens from deterioration caused by age and moisture, which can lead to breakage. The knot at the end can also loosen and cause the cord to pull out of the assembly. If the cord has not broken and the knot has just loosened, it is best to replace the cord since the loose knot indicates deterioration and the eventual breakage of the rope in the near future.

Things you need
- Allen wrenches (for some models)
- New pull rope
- Safety glasses or goggles
Locate the spark plug cover on your Murray mower and gently pull the spark plug cover off the spark plug.
Remove the screws in the cover over the engine where the pull cord is located on the Murray mower with a screwdriver or the appropriate sized Allen wrench (also called a hex key).
Look at the pull rope assembly for the specific Murray mower, which will be located right under the cover. There will be a pulley with the remainder of the rope or an obvious area where the rope should be attached. If the hole for the knot is accessible, do not remove the starter assembly. The springs can fly off and get lost and create more problems. If it is not possible to replace the starter pull rope on the Murray mower without removing the pulley, carefully unscrew the screw in the centre of the assembly that holds the pulley on the mower. Keep track of the screw and the washer or put them both back in the hole after removing the part while replacing the pull rope.
Push the end of the new starter rope into the hole and tie a double knot at the end of the new starter rope.
Look at the pull assembly where the rope is pulled from the outside of the mower. It will be offset to one side or the other of the starter pulley. The rope will have the pull side on the side with the offset.
Turn the pulley assembly to wind the rope around the pulley in the direction that pulls the rope from the offset side. Turn the pulley until it begins to get tight and then turn it backward about a turn. If the pressure on the springs below the pulley is too tight, they'll break.
Replace the starter assembly if it was removed from the Murray mower. Push the loose end of the rope through the hole in the cover. Re-attach the cover on the mower.
Slide the old rope out of the pull handle. If the starter rope goes through a guide on the handle of the Murray mower, push the end of the rope through the guide. Push the new rope into the pull handle and tie a double knot in the end of the rope. Do not trim the rope to fit until after successfully starting the Murray mower.
Replace the spark plug cover on the spark plug.
Pull the rope to start the mower. If there is not enough tension on the spring to start the mower or recoil the string, pop the cover back off and wind the rope a little tighter. If adjustments need to be made, remove the spark plug cover while rewinding the cord and replace before starting the mower. When the mower starts successfully and the cord recoils properly, push the pull handle to the proper position for the specific Murray mower, tie a knot at the location where the new pull rope meets the handle and trim off the excess rope.
