C. STARTER ROPE REPAIR AND REPLACEMENT
• A starter rope that breaks next to the pulley
can be repaired.
• Replace the starter rope if the rope breaks more
than 2-3 Inches away from the pulley as the rope
will be too short to repair properly.____________
A WARNING
Always wear eye protection when servicing the
starter rope. The recoil spring beneath the pulley
is under tension. If the spring pops out, serious
personal injury can result.
NOTE: The recoil spring, located beneath the
pulley, is under tension. If spring pops out, it
will require considerable time and effort to
reinstall. For this reason, you may want to let a
qualified service dealer handle this repair. If you
do try to repair the starter rope and the recoil
spring pops out take the unit to your dealer.

housing. Figure 41.
"- NOTE: Notice the different iengths bf the screws
and their proper locations while removing the
screws.

3. If the starter rope is not broken, release the spring
tension by pulling about 12 inches of rope from
the pulley and catch the rope in the notch as
shown. Figure 42.
NOTE: The tension on the starter spring will be
released if the rope has broken.
4. Turn the pulley counterclockwise until the spring
tension is released.
5. Remove the pulley screw in the center of the pul­
ley. Figure 43.
