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 36 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 long reach glow plug.
PROPS
Suggested propellers for this engine are 8 x 6 apc depending on the plane
being used. 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 36 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 high speed needle valve counter
clockwise about 1 3/4 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 36 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.
SERVICE
We operate a same day repair service with no labour charge - you pay only
for parts. We guarantee no repair will ever cost more than 75% of the price
of a new motor. All units returned for warranty service must be within the
