2. When starting the engine for the first time, you will need to turn the starter over the engine several times so that the pump pumps fuel into the carburetor.
3. After the engine starts, bring it to normal operating temperature at fast idle speed, at which point the fan will turn on.
4. As the engine warms up, strange odors and smoke may be emitted due to the burning of lubricants used during installation. Inspect the engine for water or oil leaks. Also inspect the connection point between the exhaust pipe and the manifold, as the bolts will most likely need to be tightened here (is performed after the engine is turned off).
5. If necessary, you can pre-adjust the idle speed, but the final adjustment will be made later, with the air cleaner already installed.
6. After you have achieved normal engine operation (no leaks, no warning lights, etc.), press the gas pedal and increase engine speed without overloading it.

7. Stop the engine and inspect it again for leaks. After the engine has cooled sufficiently, re-tighten the nuts where the exhaust pipe connects to the exhaust manifold.
8. Wait at least 2 hours for the engine to cool completely, remove the valve cover and retighten the cylinder head bolts as specified in section 9, paragraph 20. After this, adjust the valve clearances again (see section 39). Install the valve cover and air cleaner (see chapter 3). Tighten the crankshaft pulley bolt again to the specified torque. Install the hood cover, using the marks made when removing it, and add oil and coolant to the required level.
9. Turn the engine on again and adjust the idle speed if necessary. Take a test drive to check that the ignition timing and engine operation are correct. Do not overload the engine—when installing new bearings and/or pistons, treat the engine as if it were new and drive at reduced speeds, avoiding sudden acceleration and driving under tension.
10. After the first 1500-2500 km of mileage, it is necessary to retighten the cylinder head bolts again and adjust the valve clearances.
