Becoming Acquainted with your West Eurotech 50 V1 Engine
Safety Instructions and warnings
Please read through these instructions sheet in its entirety before
attempting to operate your West Eurotech engine 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
1 Keep anybody, especially small children, who can be hurt when the
engine is running, at least 20 feet away.
2 Mount 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!!
4 Use 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.
5 Mount 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.
6 Inspect 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.
7 Inspect the propeller nut and spinner between each run and tighten if
necessary. Engine vibration can cause loosening.
8 To 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.
18 Do not fly your model under or near high-tension electrical wires.
CAUTION
19 Use safety glasses or a safety shield when starting or running your
engine.
20 Do not have tight fitting cowling or oversized spinners, as they will
impede airflow to engine, causing overheating and damage to the
engine.
21 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.
22 If using a spinner of any kind, ensures that it's edges do not come in
contact with the propeller blades.
23 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 50 V1 engine.
Use good safety sense at all times. If you have any questions, do not
hesitate to contact your dealer or the Weston Service Centre.
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 ABN 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 ABN 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 50 V1 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 PP7 or PP8 long reach glow
plug.
PROPS
Suggested propellers for this engine are 9" x 6", 9" x 7", 8" x 9” and 8" x
10” depending on the plane being used. If an 8" x 8" prop is used the
manifold can be shortened by 1" to improve performance. It is very
important to balance the prop and spinner as any imbalance at high rpm
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 50 V1 Engine" to identify needle valve. NOTE:
Screw needle valve "in" for lean, "out" for rich.
1 Turn 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.
2 From the closed position, turn the needle valve counter clockwise
about 1 1/2 turns. This is a good setting to attempt to start your
engine.
3 Prepare 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.
4 Start 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
5 Carefully 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.
6 With the engine still running, carefully remove the battery connection
from the glow plug.
7 For 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 50 V1 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.
1 Pinch 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.
2 Repeat 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:
1 Always 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.
2 Foreign 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.
3 Do 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
Methanol, which absorbs water from the air, causing the corrosion to
the engine parts.
4 Do 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.
