Electrical system
The engine is equipped with an electronic ignition system completely without moving parts. Consequently, a
faulty component cannot be repaired, but must be replaced by a new component.
The spark in an electronic ignition system has a very short burn time and can therefore be interpreted as
weak and can be diffi
cult to see while troubleshooting.
Checking the ignition

Model 326
Clean the electrodes and check the elec-
trode gap.
Checking the ignition
spark
Model 326
Remove the spark plug and clean it from
soot deposits with the help of a steel
brush.
Check the electrode gap. It should be 0.5
mm.
Adjust the gap as needed to the correct
value with the side electrode.
If the electrodes are worn more than 50%
the spark plug should be changed. If the electrodes are worn more than 50%
the spark plug should be changed.
Too large a spark gap entails a great deal
of stress on the ignition module and risk
for short-circuiting.
Check if a spark occurs when attempting to
start.
Test with test spark plug no. 502 71 13-01 if
no spark is seen.
Also check that the stop switch is in the
start position.
Earth the spark plug on the cylinder and
pull sharply on the start handle.
A spark should be seen between the
electrodes.
If no spark is seen test with test spark plug
no. 502 71 13-01.
If a spark then occurs, the spark plug is
faulty.
Try a new spark plug.
