Warning: Exercise extreme
caution when carrying out
maintenance and repair work on
the ignition sysytem. The high
voltages which ocur can cause
serious or even fatal accidents!

Troubleshooting on the ignition
system should always begin at the
spark plug.
In the event of starting difficulties,
low engine power, misfiring, etc.,
unscrew the spark plug and check
that it is the approved type. Only
the spark plugs listed in the
specifications may be used. Other
makes of spark plugs are
unsuitable because they have
long-reach electrodes.
Sooted or carbonized spark plug:
- Use brass wire brush to clean
the spark plug and then blow it
clear with compressed air.
Note: Never use a steel wire
brush for this job.
Spark plug with smeared oil:
- Wash the insulator nose with
a grease solvent and blow it
clear with compressed air.
Electrode gap:
Electrode gap becomes wider as a
result of normal erosion.
The electronic (breakerless)
ignition system basically consists
of an ignition module and flywheel
and is easily accessible.
- Check the electrode gap at
regular intervals with a feeler
gauge. It should be 0.5 mm.
- Bend the ground electrode as
necessary.
Important: Always fit a new spark
plug if the electrodes are badly
eroded.
