Be sure to use an electric starter to start
the engine.

Fill the fuel tank with fuel. When filled, prevent the
fuel from flowing into the carburetor with a
commercially available fuel stopper, etc. Release
the stopper before starting the engine.

Starting procedure is as follows:

WARNING
When checking the plug element hold the plug
with tools, such as pliers, etc.
Do not hold near your face or the fuel remaining
in the filament may burn you.

Glow Plug Igniter

Pliers

Element glows when energized.

Replace the plug when the
element does not glow or is
burnt out.

Make sure that plug element glows red, and install
the plug in the cylinder head.

Never fail to check the tightness of screws
and nuts, especially engine mounting and
moving parts (e.g. throttle lever).

Be sure to use a muffler pressurized fuel feed.
Use the same fuel as you intend to employ for
actual operation of your model.

Opening and closing of the Needle-Valve

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

Opening the needle-valve

Firstly,  turn  the  needle  clockwise  slowly  until  it
stops.  The  position  it  stops  is  the  fully  closed
position  of  the  needle-valve.  Make  note  this
position for reference..
Open the needle-valve 1.5 turns.

Preparation of the starter

Install the starting shaft to the
starter securely. Poor installation
swings the starting shaft, which is
dangerous.

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 idle position. Turn the engine using
the starter until the fuel is seen to reach carburetor.
