[ NOTE ]
1. Be sure to use a gasoline-resistant fuel piping. (Do not use any silicon rubber tube).
2. Never use any alcohol fuel or alcohol added fuel, or the rubber part in the carburetor will
be damaged.
Hand flip start
Since the engine is equipped with the ultra compact C.D.I. type flywheel magneto ignition
system, it should be started according to the following procedure;
✽
The magneto system of the engine is designed in such a way that when the exhaust port
is closed by the piston, that is, when the compression stroke starts (Refer to Fig.1-A),
sparks are never produced on spark plug no matter how fast the propeller may be flipped.
Be sure to quickly flip the propeller when the edge of magnet on the rotor is approaching
the coil (Fig. 1-B). It means that the propeller should be quickly flipped about 90 degrees
in crank angle before the compression is about to start.
✽
Because of the above conditions the propeller should be mounted to the hub as shown in
(Fig. 2) and quickly flipped within the range of about 180˚ from the horizontal position.
[ NOTE ]
When the engine is mounted so the cylinder is kept horizontal, the propeller should be set at
a different angle of 90˚.
How to Start the Engine
1. Fill the fuel tank with the fuel.
2. Close the choke valve and open the throttle valve approximately 1/3 ~ 1/2 of the full open
position.
3. Quickly flip the propeller in the counterclockwise direction according to the procedure
described above. When flipped several times, the sound (popping sound) of initial
explosion is heard.
4. When the initial explosion is heard, open the choke valve, set the throttle valve at the idle
position or at the position slightly open from the idle position and flip the propeller a few
more times. Then, the engine starts.
[ NOTE ]
• Be sure to open the choke when the initial explosion is heard.
• When the choke is opened, be sure to close the throttle valve to a position near the idle
position before starting the next flipping (If the engine is started while the throttle is wide
