2. FUEL AND OIL
The VICTOR 2 / VICTOR 2 PLUS / Victor 2 Super engine uses unleaded or leaded petrol at
least 87 octane rating. The engine requires the petrol to be premixed with two-stroke oil.
STOP: Do not run the engine without ensuring that it is correctly loaded (e.g. propeller is
mounted).
Fuel contamination can be a major cause of engine failure. Ensure that your fuel container is
clean inside before you use it to fill up with fuel or oil.
Filter all fuel that goes into the fuel container. Also use a filter when transferring fuel from fuel
container into the aircraft tanks. The Victor 2 / Victor 2 Plus / Victor 2 Super engine is designed
to run on unleaded petrol or leaded petrol or avgas mixed with 2 Semi-synthetic Oil.
The Oil to be premixed with fuel must meet or exceed the specifications API, TC, JASO, FC.
It is recommended only to use a semi-synthetic 2-stroke oil like Bardahl or MixoilSynt Api or
equivalent. Use of Semi-Synthetic Oil pre-mixed in the petrol / avgas will greatly reduce the
buildup of carbon deposits in the cylinder heads and pistons. This will increase your service
intervals.

3. GEARBOX OIL
Reduction Gearbox Oil in the Simonini Type "C" reduction gearbox. Recommended Oil is
9OWX/140EP. The quantity required to fill the gearbox is 170cc with gear box upright and
225cc with gear box down.
Warning: Do not run the engine without sufficient oil in the Gear Box.
On the side of the Gear Box there are two Allen Screws which are used to inspect and indicate
the level of oil in the gear box.
It is always the lower of the 2 screws that indicates maximum oil level. The lower Allen screw
can be carefully opened to check that the oil leve1 is sufficient. Do not over fill above this level.
When the instillation requires the gear box to be fitted with the propeller shaft below the
crankshaft, the oil filler cap and the oil drain plug are interchanged.
Max Oil Level 177cc

Replace the Gearbox oil after the first 10 hours of use. The next change of Gearbox Oil is at 100
hours of use or once every 12 months, whichever comes first.
Stop: Ensure before every flight that you have sufficient oil in the gearbox.
4. FUEL PUMP
The Victor 2 / Victor 2 Plus /Victor 2 Super engine comes equipped with a Mikuni Membrane
Pump. This is a pneumatic pump operated by the pressure pulses from the crankcase of the
engine.
Install the pump 3 -4 cm higher than the crankcase pressure outlet. This will prevent a build-up
of fuel / oil mix in the lower compartment of the fuel pump, which in turn may lead to less
efficiency.
The length of the tube, which connects the engine crankcase depression to the fuel pump, should
be as short as possible, ideally less than 15 cm and not more than 30 cm long.
If your aircraft fuel tank is located more than 50/60 cm below the carburetor and fuel pump,
install an electric pump near the fuel tank. This pump will help push the fuel up to the membrane
pump and prevent vapor locks pump subsequent engine failures. Please follow the fitting
schedule of the electric pump.
Stop: The maximum fuel pressure exerted by the electric fuel pump should not exceed 0.3 bar
(4.35 psi).
When fitting an electric booster fuel pump ensure that there is fuel filter installed in line before
the pump. This will prevent the electric pump from clogging up with foreign material, which
may result in fuel starvation and resultant engine stoppage.
The electric booster fuel pump must be of the type where it allows fuel to pass through even
when it is not working.

5. BREAKING IN PROCEDURE
EACH SIMONINI VICTOR 2 / VICTOR 2 PLUS / VICTOR 2 SUPER ENGINE IS
ASSEMBLED AND RUN IN AT THE FACTORY.
EACH ENGINE IS SUBJECTED TO A DYNAMIC TEST. THE ENGINE IS
SECURELY MOUNTED ON A TEST BENCH AND A SUITABLE PROPELLER
INSTALLED ON IT.
THE ENGINE IS STARTED AND KEPT RUNNING FOR UP TO 4 HOURS AT
VARIABLE SPEEDS. TEMPERATURES AND POWER OUTPUTS ARE
REGULARLY CHECKED WHILE THE ENGINE IS BEING RUN.
THE CUSTOMER/USER IS NOT REQUIRED TO DO ANY RUNNING OR
BREAKING IN PROCEDURES ON THE ENGINE.
THE CARBURETORS ARE SET AT THE FACTORY FOR THE IDEAL
SETTINGS.
WHEN THE ENGINE IS MOUNTED ON YOUR AIRCRAFT, ENSURE THAT
BOTH CARBURETOR SETTINGS ARE EQUAL WHEN INSTALLING THE
THROTTLE AND CHOKE OPERATING CABLES.
Example of electric fuel pump that may be
used as a Booster pump

ADJUST THE CARBURETOR SLIDES UNTIL YOU GET AN 8 MM GAP UNDER
THE SLIDES WHEN VISIBLE FROM THE AIR FILTER SIDE.
TURN THE CARBURETOR AIRSCREWS FULLY CLOSE AND THEN UNSCREW
THEM BY 1 TO 1. 5TURNS.
THE ENGINE SHOULD BE RUNNING AT FULL OPEN THROTTLE WITH
6500RPM. IN THE CASE OF MAX. RPM. IS NOT DEVELOPED, CHECK
PROPELLER PITCH/SIZE AND MAIN JET SIZE.
6. STARTING PROCEDURE
NOTE: ALL SIMONINI ENGINES ARE RUN IN AT THE FACTORY AFTER ASSEMBLY.
Ensure that the engine is fitted securely to the aircraft. All electric concoctions must be checked
to be correct. All fuel lines must be securely fitted.
Stop: Ensure that there is sufficient fuel and oil in the fuel tank and enough oil in the gearbox.
Insufficient fuel and oil will cause the engine not to Start.
Ensure that there is sufficient coolant in the radiator. Insufficient coolant will cause the engine to
overheat in a matter of seconds and thereafter cause seizure of the pistons and resultant
catastrophic failure.
With the engine cold, Open fully chokes on the Bing Carburetors. Keep throttle at the idle
position.
Ensure that ignition switches are ON and that you can instantly switch them off if required.
Ensure that the aircraft brakes are on. If no brakes, ensure you have chocks under the wheels to
stop the aircraft from rolling away unintentionally.
Ensure that there is nobody near the Propeller and that the slipstream not causes damage to any
other aircraft or persons or property.

Simonini Flying SRL
Victor 2 / Victor 2 Plus / Victor 2 Super Operator s Manual
12
Engage electric starter. As soon as the engine fires, open throttle so the engine runs at slightly
over 2000/2200 rpm.
Ensure that the starter motor is disengaged from the engine. Do not run the Starter motor for
more than 5 seconds at a time.
Once the engine fires, within 10 seconds close the Chokes and the engine should be running
smoothly.
Once the engine is running for about 2 minutes, increase the RPM to 3800 -4000. Check
exhausts Gas temperatures on both cylinders. The difference should not exceed 20 ° C.
Warm up the engine until the water temperature reaches 50 ° C.
Now the engine should be ready for flight.
7. NORMAL WORKING CONDITIONS
It is recommended to use as much as gas your aircraft needs, it depends on your requirements
and as occasion may require. Reach height as soon as possible, above all if you are flying with a
delta motor.
Do not exceed maximum 6500 RPM. Do not run the engine in the climb out at Full Open
Throttle for more than 3 minutes.
Idling rpm should be 2000 rpm. Less than this may cause unnecessary vibrations. Higher idling
rpm will cause a reduction in the fuel /air mixture enrichment in the starting circuit of the
carburetor and may make cold engine start-ups difficult.
Before shut down,the engine should be run until any heat build-up from previous high power
settings (e.g. taxi back to hangar) has dissipated. Run the engine at 3000 rpm for 2 minutes and
then at 2000 rpm or smooth idle speed for a short while.
Do not idle for prolonged periods (e.g. holding point checks) as the normal rich conditions at this
carburetor setting may cause high carbon deposits on the spark plugs and piston rings causing
fouling. At low revolutions, the vibrations are high and the loads on the propeller, gearbox, and
drive train and should be avoided for longevity of the engine.

8. CARBURETOR
The Victor 2/ Victor 2 Plus / Victor 2 Super engine is equipped with 2 Bing Double Float
Carburetors. The Bing Carburetor is a piston type carburetor with float Chamber.
The following methods and combinations can adjust the Carburetor.
1. By Main Jet /Idle Jet / Needle Jet of various sizes.
2 .The Jet Needle size and position can also be varied.
3 .The Air / Fuel Mixture screw, Carburetor piston stop height can be changed.
When anyone of the above components or settings is changed, it affects the others so that other
small adjustments may be required.
Each Carburetor must be fitted with the slide axis at right angles in relation to the crankshaft
axis,both from the top and the intake side,to ensure equal fuel distribution to both cylinders.

When you receive the engine from Simonini Flying, the engine has been run in and the
carburetor settings checked.
NOTE: The Simonini Factory is at 600 meters above Mean Sea Level; thus when the engine is
run in at the Factory, it is set to produce maximum power at that altitude. If you are to operate
the engine at a very different altitude, you may need to retune the Carburetor mixture settings to
produce optimum power.
Stop: When you attach the throttle cable and choke cables, please ensure that you have both the
carburetor slides moving exactly equally up and down in unison. If not, it will cause the engine
to run rough or worse malfunction. The throttle control mechanism must enable the carburetor
slides to attain their full open position.
Ensure that aircraft movement or controls movement does not affect the movement of throttle
and choke cables. This may cause the throttle settings to change inadvertently.
Ensure that Air filters and Exhausts and Radiators are installed in place before starting the
engine. They must be in place to produce proper carburetion for the engine.
Special operating conditions or extreme altitude and or climatic changes will require different
Jetting. Contact your dealer for the correct carburetor jets setting. The Victor 2 engine/ Victor 2
Plus / Victor 2 Super engine is fitted With "Reed Valves" between the Carburetors and the
crankcase. These valves add to the efficiency of the engine in controlling carburetion and fuel
economy. The Reed Valves require changing of the VALVES after 400 hours of use.
