From the position of the max. engine speed, open the H needle
1¾ , circle (to increase fuel) to make the setting. In general,
consider 100 rpm to be the difference between the max. Engine
speed and the set engine speed. After making the setting, return
to idling. Accelerate rapidly and confirm that there are no
problems with acceleration. If acceleration is poor, open the L
needle an additional I/8th (45 degree) and confirm that
acceleration is smooth. In this case, the idling will be low, so use
the idle screw or transmitter to adjust it.
This engine has had the carburetor set at the standard position
at the time of factory manufacture. Thus, no calibration is normal
necessary. In keeping, if poor acceleration or insufficient speed
at full throttle or the like result, make adjustments in
conformance with the main points of adjustment after engine
start up. However, the idling change depending on the size of
the propeller used, which will make adjustment using the idle
screw or transmitter necessary.
Different from a glow engine, this engine does not require any
special brake in.
After 5‑10 tanks (2‑3 hours), adjust the carburetor's L and H
needles if necessary.
After about 5 hours' running. The max engine speed will be
slightly increased from initial Max speed, owing to the engine
having been conditioned.
Use a high Octane unleaded fuel (98 Octane is ideal) We
suggest starting the break in process of the engine on a test
stand; for approximately one hour. This time should be used to
get familiar with the engine. Do not run the engine at full throttle
for more than ten seconds during this test stand break in. The
reason for this is that you are not getting the normal cooling
effect that you would if the engine was in a model that was flying,
ENGINE BREAK IN
