Ignition adjustment

Turn the piston in top 0 position.

To do this we have to mount and adjust the engine timer before.

See Engine timer adjustment

Ignition adjustment.

To adjust the ignition we need a test lamp. I used a 12V lamp on 6V battery. At first it is important, to adjust clearance of the breaker contact to 4/10 mm.
The lamp is connected to ground and to the breaker contact. The moment when the lamp becomes on (ignition has to be switched on) is the ignition point. On my engine it's 3 to 5 degree before dead point (see manual of your model) by retarded ignition and 43 to 45 degree by pre-ignition with stilted centrifugal regulator.
