=== Running-in (‚‘Breaking-in‘‘) ===
For long life and peak performance, please follow the recommended running-in procedure:
* Install the engine and fit the propeller that you propose to use for flying your model. For example, If you use the propeller indicated in the „Propeller“ chapter, start the engine and run it for about 10 seconds with the needle-valve set for 6,000/6,500 r.p.m., then open the needle-valve to reduce speed to approximately 4,000 r.p.m. and run for 20 seconds at this cooler setting. Keep the throttle fully open, using only the needle-valve to reduce speed.
* Repeat this procedure, alternately running the engine fast and slow with needle-valve, but gradually extending the short period of high speed running until a total of at least 20 minutes running time has been accumulated.
* For those who do not have a tachometer, the exhaust gas colour can be a help: i.e., as the needle-valve is screwed in, the dense grey exhaust smoke will become less visible.
* Following the initial break-in of 20 minutes on the ground, run-in for a further period in the air. For the first flights, have the needle-valve set as rich as possible, consistent with adequate take-off power and, if necessary, readjust the throttle trim on the transmitter so that the engine does not stop when the throttle is fully closed.
* With each successive flight, close the needle-valve slightly, until, at the end of 10 flights, the needle-valve is set for maximum power. The carburettor can now be adjusted for optimum throttle performance as follows.
