Replacing the cable or
stop control
Dismantle the carburettor unit
to access the stop switch and
cable connections
Replacing the cable or stop
control
This stop switch is secured by a screw in
the carburettor compartment. Dismantle
the carburettor unit to access the stop
switch and cable connections.
Replacing the ignition module
The ignition module is secured by two
screws to the engine body.
When assembling the new module, the
flywheel with magnets is turned towards
the ignition module.
Place air gap gauge (.01 in./0.3 mm)
502 51 34-02 against the magnets and fit
the new module in position.
The screws should be tightened to a
torque of 6.6–8.1 lbf·ft/9–11 Nm.
Test with a test lamp
Connect a battery in series with a test
lamp to the short-circuit cable respective
engine body. With the stop switch in the
operating position the lamp should not
be lit.
Look at the test lamp while you move
the cable in different positions respective
test the function of the stop switch.
Test with a test lamp
Connect a battery in series with
a test lamp to the short-circuit
cable respective engine body.
With the stop switch in the ope-
rating position the lamp should
not be lit.
Look at the test lamp while
you move the cable in different
positions respective test the stop
switch.
Test with a meter
Connect the instrument to the short-
circuit cable respective engine body.
Set the meter for Ohm-measurement.
With the stop switch in the operating
mode, the instrument should show a
maximum or non measurable Ohm
reading.
Watch the meter reading while moving
the cable in different positions respective
test the function of the stop switch.
Should the test not indicate a fault all
that can be done is replace the ignition
module.
Test with a meter
Set the meter for Ohm-measure-
ment. With the stop switch in
the operating mode, the instru-
ment should show a maximum
or non measurable Ohm reading.
Watch the meter reading
while moving the cable in diffe-
rent positions respective test the
function of the stop switch.
Should the test not indicate a
fault all that can be done is
replace the ignition module.
