It is of vital importance, before attempting to
operate your engine, to read the general
'SAFETY INSTRUCTIONS AND WARNINGS'
section on pages 2-5 of this booklet and to strictly
adhere to the advice contained therein.
●
Also, please study the entire contents of this
instruction manual, so as to familiarize yourself
with the controls and other features of the
engine.
●
Keep these instructions in a safe place so that
you may readily refer to them whenever
necessary.
●
It is suggested that any instructions supplied
with the vehicle, radio control equipment, etc.,

SAFETY INSTRUCTIONS AND WARNINGS ABOUT YOUR O.S. ENGINE
Remember that your engine is not a "toy", but a highly efficient internalcombustion 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.
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
These cover events which
might involve serious (in
extreme circumstances, even
fatal) injury.
NOTES
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
which might ignite it. Do not
smoke or allow anyone else
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.
3
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
more powerful high-speed engines)
may eventually impair your hearing
and such noise is also likely to cause
annoyance to others over a wide area.
NOTES
•
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.
4
•
To stop the engine, fully retard the
throttle stick and trim lever on the
transmitter, or, in an emergency, cut
off the fuel supply by pinching the fuel
delivery tube from the tank.
Do not attempt to disassemble the
•
recoil starter of the 12CV-X.
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 45cm (18"). Do not abruptly
release the operating handle. Allow
the cord to rewind smoothly while
still holding the handle.
NOTES
•
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.
•
Warning! Immediately after a glowplugignition 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.

INTRODUCTION
These are overhead-valve four-stroke-cycle
engines designed for 1/10 scale radiocontrolled model cars. They are based on the
latest version of the well-established FS-26S
aircraft engine, incorporating many improved
or purpose designed parts, including a
special crankshaft, revised camshaft,
stronger valve-springs and new carburettor
with short straight through inlet tract to the
combustion-chamber for improved breathing.
The engine is distinguished by a blackanodized crankcase and rocker-cover and is
supplied complete with an O.S. Super Air
Cleaner as standard.
The FS-26S-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

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 3mm or 4-40 steel Allen
hexagon socket type. If existing holes in the
engine mount do not align perfectly with engine

mounting lugs, enlarge them slightly with a needlefile so that screws enter vertically. Avoid forcing the
screws. Secure with locknuts. If the bottom of the
recoil starter housing would otherwise touch the car
chassis, install the engine mount spacers
(supplied) between the engine's mounting lugs and
the engine mount. Use the M3x15 screws provided.
With some vehicles, it may be necessary to make
minor trimming modifications to chassis or body
when fitting the engine.
NOTE:
Where spacers are supplied joined in pairs
(see sketch), separate them as shown.

AIR CLEANER TYPE 101
This is a heavy-duty wet type air cleaner that has
been developed specifically for O.S. model car
engines. It contains specially impregnated filter
elements which prevent highly damaging dust and
dirt from being drawn into the engine through the
carburettor, yet allow engine performance to be
maintained for longer periods between element
renewals. The Type 101 air cleaner has a special
rubber body which facilitates easy yet secure
fitting, with positive sealing at the carburettor air
intake.
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 intake engages the internal annular groove
in the air cleaner: failure to do so may result in the
air cleaner falling off. See sketch, right.
FILTER ELEMENTS
¡
The elements are 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 elements. If your fingers
become contaminated, wash them with soap
and water.
¡
During storage, the oil may have become
unevenly dispersed through the elements.
This will be indicated if
element material appears patchy.
place the elements in a small plastic bag and
gently rub them between finger and thumb to
redistribute the oil.
