Correction of ignition timing angle (VAZ-2107)

When operating a car, sometimes, depending on the quality of the fuel being filled, it may be necessary to adjust the ignition timing. Make the adjustment on a warm engine. While driving on a level road in direct gear at a speed of 50 km/h, sharply press the accelerator pedal. If this causes minor and short-term detonation, then the ignition timing is set correctly. If there is strong detonation (early ignition) mark the position of the middle mark of scale 3 (Fig. 19) on the cylinder block, loosen nut 1 and turn housing 2 of the ignition distributor 0.5-1 division clockwise (to "-"). If there is no detonation (late ignition) turn body 2 0.5-1 division counterclockwise (to "+").



After adjustment, tighten nut 1 and check again for correct ignition timing while driving.
