Please read through these instructions sheet in its entirety before
attempting to operate your West Eurotech to familiarize yourself with
operation and engine features!
Don’t forget: You and you alone are responsible for the safe operation
of your engine. So act sensibly and with care at all times. This engine
is not a toy, but a precision built machine whose power is capable of
harming you or others if abused, misused, or if you fail to observe
these safety precautions.
AT ALL TIMES
1Keep anybody, especially small children, who can be hurt when
the engine is running, at least 20 feet away.
2Mount the engine properly and securely in your airplane or on a
suitable engine mount. Follow the mounting recommendations on
the airplane kit.
3 NEVER CLAMP THE ENGINE IN A VICE TO TEST RUN IT!!
4Use the correct size and pitch of propeller for your engine. See
the Propeller size Specification in this instruction sheet, consult
your model's plans, and always follow the instructions of the
propeller manufacturer.
5Mount the propeller with the curved side facing you. Tighten the
propeller nut securely against the washer and the propeller with
a correct propeller wrench. Do not use pliers.
6Inspect your propeller regularly. If propeller has any nicks,
scratches, cracks or any other sign of wear, discard it! Never
alter, repair, bend or shave a propeller.
7Inspect the propeller nut and spinner between each run and
tighten if necessary. Engine vibration can cause loosening.
8To stop engine, adjust throttle linkage to completely close and
cut off air supply. You also can cut off fuel supply by pinching the
fuel line or disconnecting the fuel line from the carburettor.
9 In any case keep your hands away from the propeller, to start
engine use only an electric starter or a “Chicken Stick”!
10 Keep glow plug clip and its cord away from spinning propeller.
11 To stop a running engine never use hands, fingers or any part of
your body, also never throw anything into a spinning propeller to
stop it.
12 Keep your face, body and any objects away from the path of the
propeller while starting and running your engine . Never lean over
a running engine
13 Stay behind engine while performing any adjustments.
14 Do not run engine in an area containing loose gravel or sand, as
these maybe thrown in your face, and could also weaken the
propeller, causing failure.
15 Follow all engine fuel warnings. Keep it in a safe place, away
from the danger of sparks, cigarettes, excessive heat, and
anything, which could ignite the fuel. Engine fuel is extremely
flammable and must be handled with great care .
16 Never run engine in enclosed area, (garage, basement, etc.)
Model engines, like automobile engines, emit deadly carbon
monoxide gas. Run your engine only in a well-ventilated open
area.
17 If you carry your model while engine is running, be very
cautious. Keep your eye on the propeller and keep it away from
you and others.
18 Do not fly your model under or near high-tension electrical
wires.
19 CAUTION
20 Use safety glasses or a safety shield when starting or running
your engine.
21 Do not have tight fitting cowling or oversized spinners, as they
will impede airflow to engine, causing overheating and damage to
the engine.
22 Do not allow loose clothing, (shirts, ties, etc.) to come near the
propeller. Keep loose objects (pencils, screwdrivers) out of
pockets to prevent them from falling into propeller.
23 If using a spinner of any kind, ensures that it's edges do not
come in contact with the propeller blades.
24 Model engines create considerable heat as they run. Do not
touch any part of your engine until it has cooled.
REMEMBER: You and you alone are responsible for the safe operation
of your West Eurotech 52 T2 engine.
Use good safety sense at all times. If you have any questions, do not
hesitate to contact Weston UK.
Operating any model with your engine requires skill and safety
precautions. A flying model can develop a great deal of power,
enough to seriously injure people and do substantial property
damage. Know what you are doing - get proper training from an
experienced modeller before operating your model!
SPECIAL NOTE
When you rotate the crankshaft of the engine by hand, you may find
that the movement of the crankshaft is not smooth and is somewhat
hard to turn when the piston is near the top end of the cylinder liner.
This is not a defect or manufacturing fault. When the engine runs, the
cylinder of the engine expands due to the heat of fuel combustion. The
top of the cylinder becomes much hotter than the bottom. The ABC
type cylinder bas been precisely machined so that when the engine is
at its optimum running temperature, the sides of the cylinder are
straight and the piston can travel freely up and down. When the
engine is cold, the top of the cylinder becomes very tight for the
piston. This is typical of most ABC engines, which have been designed
properly.
ENGINE INSTALLATION TIPS
Mount your engine securely to a rigid engine mount: The top surfaces
of the mount should be flat and parallel to prevent placing stress on
the engine crankcase. For security, use hardened steel screws, steel
hex nuts, and lock washers. To obtain the highest performance from
your engine, the engine mount should be as rigid as possible. In order
to reduce engine noise, flexible engine mounts are available. When
using a flexible mount, you may notice a loss of performance of

100-200rpm, and the engine may vibrate to some degree on the
engine mount.
FUEL TANK INSTALLATION TIPS
The fuel tank should be located close to the engine. The top surface of
the fuel tank should be slightly higher than the centre line of the main
spray nozzle in the carburettor. For West engines, this will be the
same height as the needle valve. The size and location of the fuel tank
will greatly affect the operation of the engine. When using pipe
pressure, make sure to seal all joints between the cap and the fuel
tank, and the cap and the fuel tubing. This will prevent fuel or
pressurised gas from leaking out when the engine is running.
FUEL
We recommend to only use Liquid Gold/Pro Synth 2000 fuel in your
West Eurotech 52 T2 engine, containing between 5 - 15%
nitromethane. Note that even a small change (3-5%) in nitromethane
will improve flexibility, making the needle valve adjustment less
critical and improving throttle response.
GLOW PLUG
Type and quality of the glow plug used in your engine can have a
considerable effect on performance and reliability. We recommend
operating your engine with a Weston Pro Plug PP4 or PP5 long reach
glow plug.
PROPS
Suggested props are for; 11x9” 11" x 6/8", 12.25" x 3.75", 12" x 5/6”
and 13” X 4” w depending on the plane being used. IT IS VERY
IMPORTANT TO BALANCE THE PROP AND SPINNER AS ANY
IMBALANCE AT HIGH SPEED WILL DAMAGE THE ENGINE.
BREAK-IN INFORMATION
We recommend using Pro Synth 2000 with 10% nitromethane. It is not
necessary to give the engine a prolonged break-in. The break-in
procedure should take place on the model. It is usually most
convenient to mount it in the model so that the radio control unit can
be used to control the throttle. Remember: never place the engine in a
vice!!
BREAK IN
Note: All adjustments during the break-in procedure will be made to
the needle valve only. See "Carburettor Illustration" in "Becoming
Acquainted with your West Eurotech 52 T2 Engine" to identify needle
valve. NOTE: Screw needle valve "in" for lean, "out" for rich.
1Turn the needle valve clockwise until you feel resistance. This is
the fully closed position. Do not use excessive pressure when
closing the needle valve, as this may cause damage.
2From the closed position, turn the high speed needle valve
counter clockwise about 1 3/4 turns. This is a good setting to
attempt to start your engine.
3Prepare to start your engine.
a) Use the radio control unit to open the throttle halfway.
b) Making sure that battery is not connected, place your finger over
the Carburettor throat.
c) Rotate the propeller counter clockwise 2-3 turns, until fuel flows
through the tubing up to the Carburettor.
d) Remove your finger from Carburettor once you achieve fuel flow.
Close throttle till slightly open.
e) Connect a 1.5V ignition battery to the glow plug.
4Start your engine. Use an electric starter or a “Chicken Stick” to
flip the propeller through the compression stroke. The engine
should fire after a few flips
5Carefully adjust the needle valve to attain the maximum RPM,
immediately turn the needle valve 1/4 turn counter clockwise
(rich), which will reduce RPM. This is the high-speed rich
condition and will be used during High Speed break-in.
6With the engine still running, carefully remove the battery
connection from the glow plug.
7For the next 15 minutes, or 6-8 ounces of fuel, break in the engine
by running engine at various ranges of RPM.
IDLE SETTING
You have now completed break-in. Now it is time to set the idle. Bring
RPM down to idle configuration. (See Carburettor Illustration in
"Becoming Acquainted with your West Eurotech 52 T2 engine" for
location of idle fuel adjustment screw)
Note: Try not to establish RPM below 2600, as low RPM this will
aggravate fuel problems due to low engine temperature.
1Pinch fuel line to stop fuel from going to the engine, and hold until
significant change in engine performance occurs. See a, b and c
for proper action to take pending result.
a) If RPM idles at 2600-2800, idle is set correctly. Allow idling for 3
minutes, then moving to step 2.
b) If RPM increases considerably, mixture is too rich. Carefully lean
mixture, turning idle fuel adjustment screw in 30° increments.
Once you have made adjustment, try acceleration, and then lower
RPM. Begin step 1 again.
c) If engine stops, will not idle, or will not accelerate, this indicates
mixture is too lean. Carefully enrich mixture, turning idle fuel
adjustment screw in 30° increments. Once you have made
adjustment, try acceleration, and then lower RPM. Begin Step 1
again.
2Repeat the high-speed conditions, allowing the engine to run in
the high-speed conditions longer each time before reducing to
idle. Continue this procedure until the fuel tank is empty and the
engine stops. Allow the engine to cool and refill the fuel tank.
Congratulations! Your engine should now be completely broken in. By
following these tips, you now have an engine ready to go, and you've
also learned how to make many necessary carburettor adjustments.
Have a great day flying.
ENGINE CARE AND MAINTENANCE.
By caring for and maintaining your engine, your motor will deliver long
life and peak performance. Please observe the following:
1Always keep the exterior of your engine clean to prevent it from
blackening. Use a clean cloth to remove the oil and dirt from the
outside of the engine after each use.
2Foreign matter in the fuel can cause the carburettor jet to be
partially clogged. Take care to:
a) Use clean fuel, do not leave fuel can open unnecessarily.
b) Keep fuel tank clean. Rinse out the tank with methanol or fuel
before installing.
c) Install an in-line filter in the fuel delivery tube between the fuel
tank and carburettor.
d) Install a filter between the fuel pump and the fuel tank to keep
debris from entering tank.
e) Check filters periodically and clean them when needed.
3Do not leave raw fuel in the engine at the end of the flying
session; it may cause corrosion.
a) Disconnect the delivery tube from the carburettor while engine
is still running, and allow engine to burn all remaining fuel.
b) Drain remaining fuel from tank.
c) Apply after run oil to the internal parts of the engine. The use of
after run oil can prevent corrosion and helps the engine from
becoming gummed up during extended storage. Model engine
fuels contain alcohol, which absorbs water from the air, causing
the corrosion to the engine parts.
4Do not dismantle the engine unnecessarily. This may upset
correctly mated fittings such as the cylinder and piston, or the
connecting rod and crankshaft, causing a reduction in
performance and shortening the life span of the engine. If it is
necessary to clean the interior of the engine (such as after a
crash in a dirty- area), remove only the manifold, the carburettor
(do not disassemble), and the back plate. It is possible to clean
any foreign matter from the engine at this point. Further
disassembly will void the manufacturers' warranty.
