The position for mounting the engine depends largely on the
model itse lf! F ollow the ins truction ma-nual s upplied with the
model to mount the e ngine properly.
P roc eed a s follows when s tarting a nd breaking the engine in:
1. Ma ke s ure the needle va lve is uns crewed 3 turns from
clos ed pos ition.
2. F ill fuel into the tank. Move the throttle lever to the high
position, prime the engine (push the choke button 2 ~ 3
times or put 2 ~ 3 drops of fuel directly into the carburetor)
and move the throttle lever back to the s low throttle pos ition.
C AUT ION : c arefully chec k if no dirt or de pos its clo g
the tank !
3. Attach the booster cord or one-touch glow plug
hea ter to the engine in order to electrify the glow plug.
4. Quickly pull the re coil s tarter rope (s tarter knob) s ev-e r-al
times. Only pull out 20 - 30cm of cord.
C aution: B e ca reful no t to pull out mo re tha n 50cm
of cord bec aus e y ou ma y tear it and the
s pring in s ide the recoil s tarter !
5. Once the engine is started, wait 5 ~ 10 seconds before de-taching the boos ter cord or one-touch glow plug hea ter.
6. R un the engine a nother 2 ~ 3 tanks and make sure you do
not apply full throttle. Als o afterwards, do not incre a s e R P M
abruptly! T ighten the ne edle va lve by 1/8 turns a nd continue
to run the engine, handling it gently.
C aution: After eac h tank , allo w the en-gine to c ool
7. During the break-in, a djus t the idle rpm with the throttle
valve a djustment s crew. If rotating it clock-wise (right), idle
rpm increase. Idle rpm are halfway between rpm when the
clutch engages and rpm when the e ngine stalls . S et idle
rpm towards the lower end if pos s ible.
Tighten the throttle va lve
adjus tment s crew to
increase rpm.

Uns crew the throttle

to dec reas e rpm.
8. Now a djust the nee dle valve. Its optimum s etting is when
the e ngine performs bes t and the throttle control is in the
high pos ition. If tightening it further, engine R P M will drop,
leading to engine damage. O nce you have found the needle
valve's optimum setting, uns crew it 10 ~ 20° for norma l
opera tion.
9. Once the s etting for norma l operation is done, set the
air/fuel mix-ture a djus tment s crew. S top the car and move
the throttle control from the idle posi-tion to high pos ition. If
fumes exiting the muffler are white and rpm increas e slowly,
fuel is too a bundant during the idle. To lean the mixture,
rotate the air/fuel mixture a d-justment screw clockwise (right),
ea ch time 30 ~ 40° . In the oppos ite case, if the engine s talls ,
fumes are not visible and rpm increase slowly, fuel is not
abunda nt e nough. T his time, richen the mixture and rotate
the s crew a nticlockwise (left), each time 30 ~ 40°.
No te: T he optimu m s etting may vary ac cording to
the kin d of glow plug and glow fu el us ed!
