|Having started the engine, leave it running for approx. 2 min at a higher idle speed. Then run it in for approx. 20 min, while changing revolutions from idle to 1/2-3/4 of the range and shortly holding each position - gradually prolong the holding periods. After 10 minutes of operation start opening the throttle at maximum for short periods of time. Stop the engine and let it cool down. Then restart it and check the adjustment.
If everything is all right, you can first take off. During first few flights do not overload the engine and do not let it run at high revolutions for long periods of time (very important at hot weather). Use up all fuel that was produced as a mixture with the oil that is included in the package. From now on, fuel and oil should be mixed in the proportion 40:1.
DO NOT PROCESS THE RUNNING-IN AT IDLE SPEED!
