Carburetor adjustment
The carburetor adjustment parameters should not be changed. Check the level and adjust the idle speed every 20,000 km of the vehicle's mileage or at least once a year.
Air filter element
Every 40,000 km (or more often if the vehicle is used in a dusty area) the air filter element should be replaced.
Distributor
The ignition distributor does not require maintenance, except for periodic checking and adjustment of the ignition timing angle (in engines with the ability to manually adjust this angle).
Spark plugs
Spark plugs should be checked, cleaned, the gap between the electrodes adjusted, and replaced every 10,000 km of vehicle mileage.
To unscrew and screw in spark plugs, use only the appropriate open-end wrench. The gap between the electrodes is adjusted only by bending the side electrode.
