Adjusting the spark advance angle
While in service, sometimes it becomes necessary
to adjust the spark advance angle in order to suit the
quality of the fuel used.
Perform adjustment on a warmed up engine.
Driving the car in the high gear on a level road at a
speed of 50 km/h, abruptly depress the accelerator
pedal. If this is accompanied by slight and short
time detonation, the spark advance angle is set
correctly. In case of heavy detonation (early
ignition), note the position of the middle mark of
scale 3 (Fig. 23) on the cylinder block, loosen nut 1
and turn body 2 through 0.51 division clockwise
(towards the + sign).
In case there is no detonation (late ignition), turn body 2 through 0.51 division
counterclockwise (towards the "+" sign).
Adjustments over, tighten nut 1 and repeat checking the spark advance angle on the move.
Towing the car
For towing attach the towing cable only to front towing lugs 1 (Fig. 24) or rear towing lugs 2
provided for the purpose. Tow the car smoothly, without jerks or sharp turns.
