DS 19 OPERATION No. DS 211-0 Ignition adjustments. Op. DS 211-0 132
PARTICULAR POINTS
Adjustment of ignition advance.
In order to carry out this operation it is necessary to set the ignition control in the midway position. After adjustment, do not forget to
remove the rod from the flywheel.
Adjustment of the contact breaker.
Adjust the synchronisation of the breaker.
The angle should be equal to 90 ± I and working on the contact gap (0.3 to 05 mm). When the adjustment is obtained, make sure that the
average of the two gaps is 04 mm.
Bench Test of a contact breaker.
The centrifugal advance should be between 3˚ 30’ and 7˚ 30’ at 1,000 r.p.m. and 10˚ 30’ and 15˚ 30’ at 1,500 r.p.m. On an adjustable
contact breaker, one should obtain sparks of 12 mm at 500 r.p.m. and 5 mm at 2,000 r.p.m.
TOOLS
ADJUSTMENT OF IGNITION ADVANCE
1 Put the auxiliary clutch control lever in the engaged position by pushing forward and then locking in that
position by pushing towards the top. The clutch is then in the engaged position.
2 Insert a 6 mm diameter locating pin into the special hole in the clutch bellhousing (left side).
NOTE - This hole is partly covered by the dynamo.
3 Turn the engine slowly using the starting handle, until the pin falls into the recess in the flywheel. In this
position, the engine is at the firing point (10˚ on flywheel).
4 Fit the lead from a test lamp on the condenser terminal (red terminal, blue cable) of the lower coil, the lamp
bracket connected to earth.
5 Switch on the ignition. Turn the ignition control until the distributor is in the midway position, to do this:
a) Put the control in the ‘retard” position.
b) By counting the clicks, set the lever to the middle position of its effective movement.
