If the timing can not be made by adjusting the contact brea
ker gaps within the given limits, inspect armature plate and the
contact breakers and replace if necessary.
Change of contact breaker assembly
Remove the magneto wheel by removing the nut and using the
puller. Mount new contact breaker assemblies. Adjust the gap
0,35. . .0,45 mm (0,014. . .0,018 in) as described above. Clean
the shaft end and threads and corresponding surfaces on mag
neto wheel carefully. Apply Loctite 221 or equivalent on the ta
per and threads. Mount magneto wheel and nut. Tighten nut
to 100 Nm (800 in pounds). Check ignition timing.
Note:
In case of disaseembling the armature plate, it is recom
mended to mark its position on crankcase.
Note 11 Muffler shock mounts
The attachment points of the muffler are dampened with silico
ne rubber shock mounts. When mounting the muffler it should
be checked that the attachment points are laying evenly on the
supports when the muffler pipe is in the exhaust pipe.
Use silicone rubber sheets if needed.
Use proper distance sockets to have the bolt tight with pro
per tension in the rubber.
Note 12 Engine shock mounts
The condition of the shock mounts affects the vibrations of the
engine. The rubber bushings should be in proper condition,
change the bushings when needed. The nut must always be
tightened to the socket.
Note 13 Engine retracting mechanism
The retracting crank in the cockpit is uppermost when the en
gine is fully retracted and extended. The locks on the chain
prevent the crank going over these positions. The force, when
retracting the engine fully and bringing the lever against the le
ver lock in the chain, must be less than 200 N (45 lb). If the for
ce is greater, examine the control system carefully before ad
justing the chain.
