Replace the spark plugs every 15,000 km. For a reliable engine start in the cold season, it is recommended to replace the spark plugs with new ones, even if they are still functional. Such candles can be used in the warm season.
At every maintenance:
- check and, if necessary, adjust the ignition timing;
- check and, if necessary, clean the ground electrodes with fine-grained sanding paper 4 (see fig. 107) in the cover of the ignition distributor and the contacts on its rotor 5. Wipe clean suede moistened with gasoline or other material that does not leave fibers, the outer and inner surfaces of the cover and the rotor of the ignition sensor-distributor.
