Adjustment with shim set
Remove the ignition distributor cap.
Jack up the rear of the car, engage IV gear and turn the engine crankshaft by rotating the rear wheel so that the fiber pad of the breaker hammer rests on the toe of one of the cams of the ignition distributor drive shaft.
Loosen the fixing screw of the fixed contact and adjust the gap between the contacts using a set of shims (see adjustment data in subsection «Detailed Specifications»).
Tighten the fixed contact fixing screw, turn the engine crankshaft a few revolutions to make sure that the gap between the contacts is correctly adjusted.
