play will spoil any exact timing adjustment. Turn
the flywheels only in running direction!
Note: to avoid damages on the electronic module
switch off ignition every couple of minutes, thus
avoiding uninterrupted current flow of more than
a couple of minutes. (see below „To be avoided un-
der any circumstances")
Now start the engine.
Maintenance
Once set the ignition is free of maintenance.
Nevertheless, the timing should be checked after
500 mls. If everything proves ok no further atten-
tion is needed. If not re-check after 500 more mls.
Repeated changes in timing may be a hint to me-
chanical damages of the timer shaft, bushings or
gears.
Adjusting the ignition for
optimum kickstart:
Spinning the upper rotor half in relation to the lo-
wer the timing can be optimized for easy kickst-
arting. The adjustment range goes from 10°-20°.
The leds are not needed for this adjustment, but
can be of great help. The timing for kickstarting
the engine is independant of the standard timing
for running the engine. This feature makes for an
easy start.
The two LEDs have several functions:
The red LED is used for static timing of ignition ad-
vance. The lit LED marks the moment of ignition.
While the engine is idling, the red and green LED
indicate which kickstart adjustment is set. To acti-
vate this function the engine must run just above
idle. There are three possibilities that are indica-
ted: 10°, 15° or 20° of advance.

The kickstart timing advance is adjusted by rota-
ting the upper rotor half in relation to the lower.
The LEDs can be of help as shown. Do not forget
to re-tighten the two rotor screws. Note: both LEDs
can light up intermittedly, this is no reason to wor-
ry.
What if the ignition does not work?
• All modules are tested by the manufacturer pri-
or to shipping. Before the ignition is claimed for
warranty the following items must be controlled
thoroughly.
• Check air gap (target value: <1 mm). Does the air
gap change after several kicks? (This could be a
hint for a mechanical problem.)
• With a voltmeter check between the positive coil
terminal and ground: on 6 V systems the min.
voltage must be 6 V, and 12 V on 12 V systems.
Less tension hints to bad connections or a de-
fective battery. (The module itself will work well
with e.g. 10 V, but a 12 V battery that emits only
10 V is defective and will not emit any current.)
• Check the battery state. The minimum working
voltage of the module is 4.5 V.
• Check if the timer base and the module have
good ground connection. Rust, varnish etc. will
prevent a good connection of the ground wire
and the engine case.
• Check engine ground to frame. Resistance must
be (close to) 0 ohms.
• On the ignition coil check voltage from the black
wire to ground. While turning over the cranks-
haft the voltage must alter between 6 and 0 V
