P roceed as follows:
1. Make sure the needle valve and throttle valve a djust--
ment screware s et to s tandard pos itions (s ee ~
in the previous chapter!).
2. F ill the fuel tank to a bout 80% . Apply full throttle,
prime the engine (s end only a little amount of fuel into
the carburetor by pushing the choke button 1 ~ 2 times),
then clos e the throttle.
(O n this occasion, ens ure no dirt enters the tank and
clogs the fuel line!)
3. Attach the glow plug heater or one-touch plug heater
to the glow plug and electrify it.
4. Quickly pull the s tarter knob sev-er-al times . Only pull
20 - 30cm of cord!
C a ution: B e careful not to pull the cord
beyond 50c m for it may tear!
5. Once the engine has started, make the tires s pin aloof
and s lightly open the throttle. As soon as engine R P M
have become stable, de-tach the glow plug heater or
one-touch plug heater.
6. R un the engine with this s etting for 2 ~ 3 tanks (75cc
with K YOS HO fuel tank). If engine R P M a re low a nd
the engine s ta lls though you opened the throttle,
slightly tighten the needle valve.
C a ution: With eac h tank, let the en-gine cool
off naturally (the head s hould not
feel warm-er than 50¡ C !).
If engine R PM are not stable, open the
throttle and run the car. (E ven when
applying full throttle, high-rpm cannot
be reached!)

7. After the 3rd or 4th tank, tighten the needle valve 30¡
with every tank and apply more throttle.
8. R epeat step 7. When your car reaches top speed
when running down a s traight a t full throttle, you have
found the optimum s etting for the needle valve and the
break-in is completed. If you tighten the needle valve
furthermore, exhaus ts will get invi-sible and R P M s ag.
R un-ning the engine with such setting will definitely
dama ge it. If the needle valve is too tight, unscrew it
immediately. F or normal running performa nce, un-screw the needle val-ve 10¡ to 20¡ from the optimum
setting.
Note: The optimum s etting may s lightly vary
according to the glow plug a nd glow
fuel us ed as well as to c hanging
weather con-ditions !
C a ution: Do s tep 8 only when running your
car! T he engine will be dama ged if
the wheels are s till s pinning aloof.
