close the needle-valve, and turn
the needle counter-clockwise to
open the needle-valve as shown
in the sketch.
Opening the needle-valve

stops. The position it stops is the fully closed
position of the needle-valve. Make note this
position for reference..
Open the needle-valve 1 turns.

Checking the rotating direction of the starter
Make sure that the starter rotates
to the direction shown in the
sketch. If the direction is reverse,
reverse the leads on battery.
Inserting the starter shaft
Insert the starting shaft into the
shaft cup securely.
Priming
Without heating the glowplug, open
the throttle a little from the idling
position. Turn the engine using the
starter until the fuel is seen to reach
carburetor.
Preparation of starting
Make sure that the transmitter
throttle stick is at the fully closed
position and the throttle trim at
center position, and make sure that
idle-up switch on the transmitter is
off. Hold the rotor head by hand so
that rotor cannot rotate when the
engine is Started. Also, steady the
model with a foot on the landing-
gear skid.
