●ENGINE STARTING & BREAK-IN
Proceed as follows when starting and breaking the engine in:
1. Make sure the High-Speed Needle is unscrewed 3 turns
from closed position.
Add fuel to the fuel tank.
Move the throttle lever to the slow position.
CAUTION: Make sure the fuel tank and fuel bottle do not
contain any foreign particles before adding fuel.
2. Cover the exhaust exit with your finger and gently pull the
recoil starter and make sure fuel has been sent down the
fuel tube to the carburetor.
CAUTION: Danger of burns. Allow the muffler to cool
down before restarting the engine.
3. Attach the booster cord or one-touch glow plug heater to the
engine in order to electrify the glow plug.
4. Quickly pull the recoil starter rope (starter knob) several
times. Only pull out 20 - 30cm of cord.
Caution: Be careful not to pull out more than 40cm of cord
because you may tear it and the spring inside the recoil
starter!
5. Once the engine is started, wait 5 ~ 10 seconds before
detaching the booster cord or one-touch glow plug heater.
6. Run the engine another 2 ~ 3 tanks and make sure you do
not apply full throttle. Also afterwards, do not increase RPM
abruptly! Tighten the High-Speed Needle by 1/8 turns and
continue to run the engine, handling it gently.
Caution: After each tank, allow the engine to cool off
naturally!
7. During the break-in, adjust the idle rpm with the Idle Speed
Screw. If rotating it clockwise (right), idle rpm increase. Idle
rpm are halfway between rpm when the clutch engages and
rpm when the engine stalls. Set idle rpm towards the lower
end if possible.
Tighten the Idle Speed
Screw to increase rpm.

＊Idling RPM is when the flywheel is rotating while the
clutch bell remains static.
Unscrew the Idle Speed
Screw to decrease rpm.

8. Measuring the temperature of the area around the glow plug
while adjusting the High-Speed Needle position is regarded
as the best way to achieve the Idle Speed Screw setting.
No.36207 Thermometer Mini is great for this purpose.
Aiming for a temperature of 120° C is recommended.
9. Once the setting for normal operation is done, set the
Low-Speed Needle. Stop the car and move the throttle
control from the idle position to high position. If fumes
exiting the muffler are white and rpm increase slowly, fuel is
too rich during the idle. To lean the mixture, rotate the
Low-Speed Needle clockwise (right), each time 30 ~ 40˚. In
the opposite case, if the engine stalls, fumes are not visible
and rpm increase slowly, fuel is not rich enough. This time,
richen the mixture and rotate the screw counterclockwise
(left), each time 30 ~ 40˚.
Note: The optimum setting may vary according to the
kind of glow plug and glow fuel used!
Note: The optimum setting may vary due to changing
weather conditions!
The best position of High-Speed Needle must be opened
between 2-1/2 and 3 turns from the fully closed position.
Warning! Closing the High-Speed Needle too much
carries the risk of seriously damaging the engine.
Caution: Perform these adjustments (from step 8) only
while running your car on the ground! The
engine will be damaged if the wheels are off the
ground and spinning freely.
●MAINTENANCE
＊After running the engine, draw out any leftover fuel from the
fuel tank.
＊Draw out fuel from inside the engine as well. Fuel that
remains inside the engine, may clog the engine and make it
difficult to start.
＊Remove any dirt from the outside of the engine using
methanol and a brush. Do not allow fire or any excessive
heat source to come into contact with methanol which is
highly inflammable! This may cause fire!
Never use gasoline or thinner when
cleaning!
This may cause Fire !
