Lock the bottom of the pull start in place with the locking pliers, lock the pliers in a vice and use the 24mm wrench to undo the bolt in the top side of the pull-start. After loosening the top bolt, unwind the bottom section with your hands and remove it (do not lose the clip around the bottom of the pull-start). Then remove the top section, revealing the pull-start coil.
There should be a U-shaped bend on the inside end of the starter coil, often this bends and is what causes the pull-start to lose tension. Bend the coil back into shape (in the appropriate direction, so as to latch onto the tab on the metal section of the pull start), if need be you may cut a portion off the end of the coil if it is beyond repair, do not remove more than is necessary. When working with the starter coil be careful not to let the entire coil unwind.
Reassemble all parts of the pull-start, when replacing the bottom bolt ensure that it is aligned correctly with its clip and (this can be difficult as it tends to move during tightening, so keep an eye on it).
If the cord doesn’t wind in all the way it may be necessary to spin it around the pull-start one or two more times (click here for video). If the cord is now winding back without any problems reassemble your mower.
