Although Stihl weed eaters are reliable tools, starter ropes and recoil springs will break. The entire pull start assembly is behind the pull cord cover. Disassembling the pull start on the Stihl weed eater is not difficult. Stihl uses Torx head fasteners to secure the various components to the crankcase. If you do not own a set of Torx drivers, now is a good time to invest in a good set. Torx drivers and replacement pull cords are available at home improvement centres.

Pull the spark plug wire from the top of the spark. Grab the wire by the boot end that attaches to the spark plug with your fingers and twist the boot slightly. Pull the boot off the plug.
Use a Torx driver to remove the four screws securing the pull cord cover of the crankcase.
Lay the cover on a flat surface with the inside of the cover facing toward you. Use the Torx driver to remove the centre screw that secures the pull cord rotor to the cover. Pull the screw and the washer away from the rotor.
Pull the rotor off the starter post with your fingers. The rewind spring is under the pull cord rotor, so pull the rotor away slowly. If you feel any resistance, twist the rotor clockwise; this should disengage the rewind spring.
Pull out the rewind spring if the spring is broken or damaged. If you are not replacing the spring, do not remove it. The rewind spring is set to recoil the rope back onto the rotor. If you have to remove the spring, wear leather gloves and lift the spring off the starter post. Slowly release your grip on the spring to allow it to unwind.
