Står i manualen ja. Kjør den på full gass, men siklende rik (at den får så mye fuel at den neste ikke går), så lean den helt ut, så rik igjen osv. Bare 10-30 sek. på hver innstilling. Etterhvert som du gjør dette vil du se at du må skru nåla mer og mer inn for å få den lean. Når du ser at den er lean på samme dysenålinnstilling hele tida er den 100% innkjørt.
Men du kan også bare kjøre den rik et par tanker. Det er i praksis ingen forskjell.
RUNNING-IN ("Breaking-in")
All internal-combustion engines benefit from extra
care when they are run for the first few timesknown
as running-in or breaking-in.
This allows the working parts to mate together under
load at operating temperature. Therefore, it is vitally
important to complete the break-in before allowing the
engine to run continuously at high speed and before
finalizing carburetor adjustments.
However, because O.S. engines are produced with
the aid of the finest modern precision machinery and
from the best and most suitable materials, only a
short and simple running-in procedure is called for
and can be carried out with the engine installed in the
model. The process is as follows.
Install the engine with the propeller intended for
your model. Open the needle-valve to the advised
starting setting and start the engine. If the engine
stops when the glow plug battery disconnected,
open the needle-valve to the point where the engine
does not stop.Run the engine for one minute
with the throttle fully open, but with the needlevalve
adjusted for rich, slow "four-cycle"operation.
1.
Now close the needle-valve until the engine
speeds up to "two-cycle"operation and allow it to
run for about 10 seconds, then reopen the needlevalve
to bring the engine back to "fourcycle"
operation and run it for another 10 seconds.
Repeat this procedure until the fuel tank is empty.
Re-start and adjust the needle-valve so that the
engine just breaks into "two-cycle" from "fourcycle"
operation, then make three or four flights,
avoiding successive "nose-up" flights.
During subsequent flights, the needle-valve can be
gradually closed to give more power.
However, if the engine shows signs of running too
lean, the next flight should be set rich. After a total
of ten to fifteen flights, the engine should run
continuously, on its optimum needle-valve setting,
without loss of power as it warms up.
After the completion of the running-in adjust the
carburetor at optimum setting referring to
MIXTURE CONTROL VALVE ADJUSTMENT
section and SUBSEQUENT READJUSTMENT
section.

Slowly advance the throttle to its fully open position,
then gradually close the needle-valve until the
exhaust note begins to change. (4-cycle to 2-cycle)
At this point, disconnect the battery from the
glowplug, taking care that the battery leads or
glowplug clip do not come into contact with the
rotating propeller. If the engine stops when the
battery is disconnected, close the needle-valve about
30° and restart.
As the needle-valve is closed slowly and gradually,
the engine r.p.m. will increase and a continuous highpitched
exhaust note, only, will be heard. Close the
needle-valve 10-15° and wait for the change of r.p.m.
After the engine r.p.m. increases turn the needlevalve
another 10-15° and wait for the next change of
r.p.m. As the speed of the engine does not instantly
change with needle-valve readjustment, small movements,
with pauses between, are necessary to arrive
at the optimum setting.
Husk, dette er ikke en ring motor,men en abn motor.

How do I break in my new ABN engine (for example, 40FX)?
Your ABN engine must be broken-in at full throttle. You don't want to run it too rich. Too- rich running will not allow it to warm to proper temperatures, so the liner does not get properly seated. Lean it until it is running just out of what is known as "four-cycle" mode, then gradually work leaner with each run. You can lean it to peak RPM as soon as the engine will accept it.
You should prop your engine to allow higher RPMs. ABN engines work better at higher RPM. You should also use a fuel that contains castor oil in the lubrication mix. Castor oil helps the engine run well and is the better lubricant for our ABN engines. All-synthetic fuels have been known to cause difficulties in running at times.
Once properly broken-in, your ABN-type engine will serve you well and deliver lots of reliable performance.

Lar jeg den bare stå på tomgang i 2-3 tanker med veldig rik blanding da?
Skal jeg skru ut (mot klokken) til den går kjemperik også bare la den gå sånn?
Og etter 2-3 tanker så leaner jeg en inn og da er den ferdig?
Og kan jeg bruke en 11x7 propell under innkjøring?
Siden dette er en abc motor så gjør du bare som JW beskrivte over.
*1= Sta bak flyet med motoren på tomgang.
*2= Gi full gass.
*3= La den stå på full gass hele tanken, men juster turtallet ved bruk av dysenåla.
Når motoren er på full gass, skru ut dysenåla såpass mye at motoren mister turtall og såvidt vil gå, la den stå slik i 15 sekunder, så skrur du inn dysa til du hører stor økning i turtall, la den stå slik i 15 sekunder og repeter dette til tanken er tom. Gjør dette 2-3 tanker så er motoren som regel klar
Jo det kan du, men det tar jo hele dagen, hehe. Måten jeg beskrev over, er en veldig normal og ikke minst en god måte og kjøre inn en abc motor på. Hadde det vært en ring motor så hadde ting vært annerledes, men abc motorer en greie og kjøre inn Driver selv på å kjøre inn en Sc 36 motor, den virker sprekere enn de fleste 40 motorer faktisk!
Kjører du inn en ABN motor på tomgang blir den ikke gammel. Du må ha full gass for at motoren skal bli ordentlig varm. Går motoren for kald vil ikke sylinderforingen ekspandere nok som resulterer i at stempelet ”høvler” ut belegget i sylinderveggen.
Gi full gass og regulere turtallet med dysenålen som Jon skrev. En tank på bakken burde være nok før du tar motoren i bruk. I luften vil den få en mer riktig luftkjøling enn på bakken.
