2. With the ignition system turned off and the spark plugs removed (see section 3) crank the engine until oil pressure appears in the system.
3. Install the spark plugs and turn on the ignition system (see section 3).
4. Start the engine. There may be some delay in starting to allow the fuel pressure in the system to build up.
Note: If backfiring occurs in the carburetor, check the ignition timing and valve adjustment.
5. After starting, warm up the engine to operating temperature at idle speed and leave it at this mode for another 15 minutes. Stop the engine and check the fuel level, oil level and coolant leaks.
6. On a road with little traffic, accelerate at full throttle from 50 to 80 km/h, then slow down again to 50 km/h with the throttle closed. Repeat the acceleration-coasting 10-12 times. This will help the rings to position themselves relative to the cylinder walls. Check for oil and coolant leaks.
8. Run the engine for the first 800 km without violating traffic regulations for maximum speed. Constantly monitor the oil and coolant levels. During the run-in, slightly increased oil consumption may be observed.
9. After running-in (800 km mileage) change the oil and oil filter.
10. After 2000-3000 km, change the oil and filter again.
