Remember that your engine is not a "toy", but a highly efficient internal-
combustion machine whose power is capable of harming you, or others, if it is
misused.
As owner, you, alone, are responsible for the safe operation of your engine, so act
with discretion and care at all times.
If at some future date, your O.S. engine is acquired by another person, we would
respectfully request that these instructions are also passed on to its new owner.
SAFETY INSTRUCTIONS AND WARNINGS ABOUT YOUR O.S. ENGINE
The advice which follows applies basically to ALL MODEL ENGINES and is
grouped under two headings according to the degree of damage or danger
which might arise through misuse or neglect.
WARNINGS NOTES
These cover events which
might involve serious (in
extreme circumstances, even
fatal) injury.
These cover the many other
possibilities, generally less obvious
sources of danger, but which, under
certain circumstances, may also
cause damage or injury.

WARNINGS
Model engine fuel is
poisonous. Do not allow it
to come into contact with
the eyes or mouth. Always
store it in a clearly marked
container and out of the
reach of children.
Model engine fuel is also
highly flammable. Keep it
away from open flame,
excessive heat, sources of
sparks, or anything else
whichmightigniteit.Donot
smokeorallowanyoneelse
to smoke, near to it.
Never operate your engine in an
enclosed space. Model engines, like
automobile engines, exhaust deadly
carbon-monoxide. Run your engine
only in an open area.
Model engines generate
considerable heat. Do not
touch any part of your
engine until it has cooled.
Contact with the muffler
(silencer), cylinder head
or exhaust header pipe, in
particular, may result in a
serious burn.

This engine is intended for model cars.
Do not attempt to use it for any other
purpose.
Mount the engine in your model
securely, following the manufacturers'
recommendations, using appropriate
screws and locknuts.
Fit an effective silencer (muffler).
Frequent close exposure to a noisy
exhaust (especially in the case of the
most powerful highspeed engines)
may eventually impair your hearing
and such noise is also likely to cause
annoyance to others over a wide area.
The wearing of safety glasses is also
strongly recommended.
Take care that the glowplug clip or
battery leads do not come into contact
with rotating parts. Also check that the
linkage to the throttle arm is secure.
For their safety, keep all onlookers
(especially small children) well back
(at least 20 feet or 6 meters) when
preparing your model for running.

NOTES
To stop the engine, fully retard the
throttle stick and trim lever on the
trans-mitter, or, in an emergency, cut
off the fuel supply by pinching the fuel
delivery tube from the tank.
•
Warning! Immediately after a glowplug-
ignition engine has been run and is still
warm, conditions sometimes exist
whereby it is just possible for the engine
to abruptly restart if it is rotated over
compression WITHOUT the glowplug
battery being reconnected.
•
Do not attempt to disassemble the
recoil starter of the 40S-CX.
If you do so, the very strong spring
inside will be suddenly ejected. This
can be very dangerous.
Do not extend the starter cord more
than 40cm (16"). Do not abruptly
release the operating handle. Allow
the cord to rewind smoothly while
still holding the handle.
•
•
Pull the operating handle straight out
when starting the engine, so that the
cord does not rub against the vehicle
body or engine. This will help prevent
the cord from being damaged by
abrasion or engine heat.
•

These are overhead-valve four-stroke-
cycle engines designed for 1/8 scale
radio-controlled model cars.
The engine is distinguished by a black-
anodized crankcase and rocker-cover
and is supplied complete with an O.S.
Super Air Cleaner as standard.
The FS-40S-CX is equipped with a built
in recoil starter system which eliminates
the need for a separate electric starter
and starter battery.

INSTALLING THE GLOWPLUG
Install the washer on the

cylinder-head, making sure that
it is not cross-threaded before
tightening firmly.

ENGINE INSTALLATION
Make sure that the vehicle's engine mounting
surfaces are level and in the same plane. Poor
installation may cause distortion of the crankcase,
bearings, etc., resulting in erratic running and loss
of performance. The recommended screws for
securing the engine are 3.5mm or 4-40 steel Allen
hexagon socket type. If existing holes in the
engine mount do not align perfectly with engine

INSTALLATION OF THE CARBURETOR
As delivered, the engine has its carburetor lightly
fit into the intake boss. Secure it as follows.
Loosen the retainer screw,and remove the
carburetor. Place the rubber gasket at bottom
of the intake boss, and rotate the carburettor
to its correct position and make sure that it is
pressed well down into the intake boss,
compressing the rubber gasket, before
retightening screw.
Rotate the retainer screw gently until it stops,
then tighten a further 60-90˚.
Do not overtighten the screw as this will
damage the carburettor body.

AIR CLEANER TYPE 102S
INSTALLATION OF AIR CLEANER
Carefully clean the
carburettor, removing any
old adhesive or sealant
that may have been
previously used on the
outside of the air intake.
•
Press the air cleaner body firmly over the
carburettor air intake. Make sure that the outer
rim of the air intake engages the internal
annular groove in the air cleaner: failure to do
so may result in the air cleaner falling off.
•
It has a single filter element and is intended
primarily for circuit racing, where conditions are
less damaging than the very dusty, loose surfaces
of off-road operation for which the double-element
Type101and102AirCleanersarerecommended.
The lower height of the Super Air-Cleaner 102S
also facilitates easier installation in cars where
available space may be restricted.
NOTE:
Where spacers are supplied joined in pairs
(see sketch), separate them as shown.
Either face may be placed downwards.
Secure with locknuts. If the bottom of the recoil
starter housing would otherwise touch the car
chassis, install the engine mount spacers

NOTES CONCERNING THE RECOIL STARTER
( FS-40S-CX ONLY)
REMINDER!
◆
◆
Do not attempt to disassemble the recoil
starter. If you do so, the very strong spring
inside will be suddenly ejected. This can be
very dangerous.
Do not extend the starter cord more than
40cm(16"). Do not abruptly release the
operating handle. Allow the cord to rewind
smoothly while still holding the handle.
Pull the operating handle straight out when
starting the engine, so that the cord does
not rub against the vehicle body or engine.
It is advisable to replace the filter element with
a new one after not more than one hour of
running time. Always remove contaminated
elements carefully, to ensure that dirt cannot
enter the carburettor.
REPLACEMENT OF ELEMENT
•
Position the air cleaner correctly, so that it
does not foul the cylinder-head or obstruct the
needle-valve.
•
FIT THE FILTER ELEMENT
The element is already impregnated with a
special filter oil. As this oil is very sticky, take
care, when handling it, to prevent dust or dirt
from adhering to the element. If your fingers
become contaminated, wash them with soap
and water.
During storage, the oil may have become
unevenly dispersed through the element. This
will be indicated if the blue colour of the element
material appears patchy.
•
•
Insert beneath flange
In this case, place the
element in a small plastic
bag and gently rub it
