Check of a cover of the distributor of ignition
Remove the cover of the ignition distributor, to do this, wring out both side clamping brackets with a screwdriver.
The lid must be dry inside.
Check the internal connection contacts for wear and corrosion, clean the contacts with sandpaper if necessary.
Check the ease of movement and the degree of wear of the central carbon contact. To do this, press the contact with your finger.
Check up absence of currents of leakage on a cover of the distributor of ignition. Leakage currents are identified by thin, uneven marks on the surface of the distributor cap.
Wipe the ignition distributor cap with a clean, dry cloth and inspect it for microcracks. If required, replace the ignition distributor cap.
Remove the ignition distributor slider and check for microcracks. Both contacts, in the middle and along the edge, should shine; if necessary, clean the contacts.
Apply one drop of oil to the felt on the distributor shaft.
Put on the ignition distributor slider, while snapping the protrusion in the slider into the recess of the ignition distributor shaft. Turn the ignition distributor slider in both directions, checking the reliability of fastening.
Establish a cover of the distributor of ignition.
Checking electrical connections
Check the security of all electrical connections on the ignition coil and on the ignition distributor.
Clean corroded connector contacts with sandpaper or a wire brush, spray with contact spray if necessary.
Contacts must be dry, otherwise clean contacts and spray with contact spray.
Bend the ignition wires and check for cracking of their insulation. If required, replace the ignition wires.

Checking ignition systems
Attention! Spark plugs are checked on a cold or warm engine. Removing the spark plugs while the engine is hot can damage the threads of the spark plug holes in the light metal cylinder head.
Conventional spark plugs installed on cars manufactured before August 1985 should be turned out every 15,000 km, cleaned and the distance between the electrodes adjusted.
Extended life spark plugs are replaced every 30,000 km.
Check the distance between the electrodes and compare with the data tab. 8.
Single electrode spark plugs «masses» it is necessary to adjust the distance between the electrodes. There is a special tool for this. In its absence, knock on the side of the electrode «masses» to reduce the distance between the electrodes. When bending the electrode «masses» with a small screwdriver, rest it against the edge of the thread of the candle, but in no case against the electrode «masses», since it could be damaged.
Screw in the spark plugs by hand until they touch the cylinder head.
Tighten the spark plugs with a spark plug wrench to a torque of 25 Nm.
Attention! If a torque wrench is not available, screw in the spark plugs by hand until they are in contact with the cylinder head. Then the new flat seat spark plugs are tightened another 90 degrees, and the new taper seat spark plugs and non-new flat seat spark plugs are further tightened by about 15 degrees. If the spark plugs are removed, they may break off or damage the threads in the cylinder head. In this case, the threads must be repaired with a UTC or Heli-Coli insert.
Connect the spark plug tips according to the ignition sequence. Wiggle in different directions to make sure that the spark plug tips and ignition wires are securely fastened.
