1-/ 2-Cylinder
CAUTION
Use proper precautions when performing tests
with the engine cover removed. Do not wear
loose clothing or jewelry. Keep hair, hands, and
clothing away from the flywheel and other
moving parts.
CAUTION
When repairs are complete, make sure all ignition
and electrical leads are properly routed and
clamped in their original positions and the start-
in-gear prevention system must be tested before
returning engine to customer.
FIywheel
Replacing the exciter coil or coil plate assembly requires the
removal of the flywheel, see Section 4, Flywheel, for the proper
procedure.
NOTE
Flywheel magnets must be of a particular strength in
order to run the ignition system. Weak magnets can
cause low ignition voltage which may affect engine
performance. Flywheels seldom go bad and would
only be replaced as a last resort in solving an ignition
problem.
Carefully inspect flywheel
(1)
for cracks, chips, and
worn taper after it is removed. Also inspect the
magnets
(2)
for cracks and chips and make sure they are firmly
attached to the flywheel.
Exciter Coil
NOTE
Disconnect negative battery cable from battery
before removing exciter coil.
This procedure assumes exciter coil is available as a
separate replaceable component. Some engine
configurations might require replacement of entire
coil plate assembly. Check current Parts Catalog for
availability.
