advance degrees indicated by the stroboscopic
lamp.
- Check that the advance degrees match the rev-
olution speed as indicated in the tables.
- In case of abnormal values, check the Pick-Up
and the control unit supplies (positive-negative);
replace the control unit, if required.
- A new control unit prevents the engine from ro-
tating at over 2,000 rpm.
- The programmed control unit allows the engine
revolution within the prescribed limits.
