NOTE: If the starter was failing to engage the fly-
wheel, and the edges of the slots inside the
cup are burred or damaged, replace the
starter cup.
NOTE: If the starter cup is replaced, the complete
starter should be replaced as well, to prevent
a repeat failure.

turning by:

the spark plug hole.
NOTE: Leave part of the rope sticking out of the
engine so that the rope can be removed later.

nut.
