Can any one tell me how to replace a pull cord on a tryo bit 6.5. It totally broke off and O am nervous about replacing it but my grass needs mowed bad.

Remove the blower housing,
Remove the old cord
Rewind the spring
Insert new cord from inside or outside which ever is easiest,
Put knot in the end to the inside,
Pull loose rope through the holes
Tie a knot about a foot from the end of the rope
Let go,
If you wond the spring correctly, it will take the rope into the rewind starter assembly up to the knot,
Reinstall the blower housing,
Pull bail brake handle,
Pull rope through the eye bolt
Put on the handle,
USES ABOUT 7 FOOT OF ROPE.
