The rewind spring is correctly
tensioned when the starter grip sits
firmly in the rope guide bushing
(arrow) without drooping to one
side. If this is not the case, tension
the spring by one additional turn.
When the starter rope is fully
extended, it must still be possible to
rotate the rope rotor at least another
half turn before maximum spring
tension is reached. If this is not the
case, reduce spring tension since
there is otherwise a risk of
breakage.
To reduce spring tension:
Pull the rope out, hold the rope rotor
steady and take off one turn of the
rope.
