[ 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.
1. Avoid starting engine by hand flipping propeller as it may cause injury. Make sure to start
by using built-in spring starter or large size electric starter with reduction gear (available
on the market) .
2. Make sure to put on thick glove when starting engine.
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. Rotate the propeller counterclockwise until the piston passes over its top dead point.
Then rotate it clockwise for 1/2 ~ 3/4 revolution to wind up the spring, and release the
propeller. Repeat this several times until the initial firing sound is heard.
4. Upon hearing the initial firing open the choke valve and set the throttle to the idle or
slightly open position. Take the same procedure as mentioned above step 3, and the
engine will start.
[ NOTE ]
• Be sure to keep holding propeller firmly by other hand while winding up the spring for
starter.
• Be sure to open the choke when the engine first fires.
• When the choke is opened, be sure to close the throttle valve to a position near the idle
position before starting the engine (If the engine is started while the throttle wide open it will
develop a high level of power and thrust which can be very dangerous).
How to Stop the Engine
For stopping the engine, the black lead
wire from the coil should be grounded to
the engine body, or the throttle valve
should be closed completely.
The carburetor is provided with 3 adjust screws which are set to the best (approximately)
positions by our company, but they may need a little adjustment depending on the
temperature, atmospheric pressure (altitude), etc. of the area where the engine is used. Start
the engine without making any adjustments. Make readjustments only when the engine
shows any mal-functioning.
[ NOTE ]
Be sure to stop the engine before starting the adjustment, thus ensuring safety.
Idle Screw: Turning this screw clockwise increases the idling R.P.M. Turning it
