IGNITION UNIT MOUNTING
FUEL AND PIPING
ITEMS TO CONFIRM BEFORE STARTING THE ENGINE

Fuel pump for gasoline
Electric starter device
Make sure that during the fueling process. The fuel does not
come in contact with the battery or the fuel that has overflowed
does not come in contact with the muffler.
Make sure there is no loosening off or abnormalities with the
tightening, etc., of each part of the engine and model.
Are there any problems with the linkage (in terms of its direction
and actuation stroke)?
Has the battery been sufficiently charged?
Are there any propeller abnormalities (scratches, deformation .
etc)
Re‑tighten the muffler (for starting an engine from the second
try on).
Make sure that the fuel pipe and the wiring of the DC ignition
unit and the like do not pass through the engine's muffler body
and that the wiring and fuel pipe are not interferences.
Starting the engine By Starter
Close the choke lever and open the throttle valve 10%to 15%.
Pressing the tip of the starter to the engine's spinner. Press the
start switch for 1‑2 second and let the engine rotating until saw
some fuel flew out from choke .
Switch on your ignition
If the engine has made an explosive sound. Suspend the
starting operation and start by opening the choke lever and
rotating the engine using the starter. (Opening or closing the
choke lever during engine operation is prohibited.)
*If the engine will not start, leave the choke lever in the open
position and

rotate the engine by pressing the starter for 1‑2 second. If the
engine still not starts, repeat this operation 2 or 3 times.
(A) Points in starting
During the first start up operation, does the fuel reach the
carburetor? If the fuel reaches the carburetor, the choke should
be open position.
Is the ignition switch on?
If there is absolutely no explosive sound, remove the spark plugs
and check it.
If the spark plugs became wet condition by over choking, dry it
out, open the choke, and restart.
(B) Cautions in starting
One person must restrain the fuselage during the start up
operation. (Thus start up is prohibited).
With the spark plugs removed when using the starter for rotation
or rotating the propeller by hand. Make sure the ignition switch
has been turned off.
Rotation should be left. Confirm the direction of motor rotation in
advance If the engine
(A)ADJUSTING THE IDLING
After engine start up, set the idling at about. Turn the L needle in
(to reduce fuel), and search for the position for the max. Engine
speed from that position, turn the L needle about 1 1/4 circle, set
the idling speed with the idle screw or the transmitter.
(B)ADJUSTING NUMBER OF ROTATIONS AT FULL
THROTTLE
Achieve full throttle slowly. When the engine speed stabilizes,
turn the H needle in and out to locate the position for the max
rpm.
ADJUSTMENTS AFTER ENGINE START UP

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

Note:
For break‑in a smaller propeller is recommended.
Important:
1.Remember that when the engine running ever person must stay
behind the line of the rotating propeller; never to the side or the
front!
2.The engine needs 12‑20 hours running time for the break in
process to be 100% complete.
Engine Cooling
A proper cooling system is vital for any engine. An air cooled
engine requires an appropriately sized air intake. Also to keep this
air cooling process working the incoming air must be exhausted.
Further, the exhaust air outlet should be four times (4X) the size of
the cool air intake.
Example:
.10 square inches of air intake area would require
.40 square inches of exhaust air outlet area
It is up to you to insure that the air flows freely to, over, and away
from, the hot cylinder(s) and muffler(s). Please refer to Engine
Installation for motor box considerations, and to the following tips
on baffling.
STOPPING THE ENGINE
To stop the engine, either use the transmitter to achieve full closed
throttle or turn the battery switch off. When you have stopped the
engine and not operating the engine, make sure to keep the
battery switch off.

Because this engine uses a battery for power supply, the engine’s
continuous running time will depend on battery capacity. Please
refer to the table on the right for guidelines.
To ensure safe use of the engine, make sure of the items specified
the table below.
