Trouble shooting

Examine the ignition system first when
the engine does not start.
Check the ignition spark
Earth the spark plug against the cylinder
by using the spark plug socket to extend
the earth cable as the air duct prevents
direct earthing.
Move the stop button to the operating
position. Pull the starter handle as with
starting.
Do the following if no spark occurs.
Faulty spark plug
Replace the spark plug with the test spark
plug 502 71 13-01. If there is spark now
the spark plug is defective. Replace the
spark plug.
If there is no spark the next step is to
check the ignition lead.
Faulty ignition lead
1, 2. Pull up the rubber seal by the igni-
tion module and unscrew the ignition
lead from this.
3. Insert a pair of pointed pliers in spark
plug connection and pull out the spring
and cable end.
4. If the connection is defective, the igni-
tion lead can be shortened slightly. Make
a new hole in the cable with a awl and fit
the connection spring.
5. The adjoining simple connection can
be used to check that the ignition lead is
not broken. The battery is connected in
series with a test lamp.
Alternatively, a resistance measurement
can be made using a Ohm meter.
Damaged short-circuit cable
Check that the short-circuit cable is in
position. Examine the cable for signs of
wear or damage where it may have
reached the engine body and in doing so
create a short circuit.
Test the stop switch and the cable to
this from the ignition module with one
of the following methods.
