INTRODUCTION
Congratulations on having chosen the MZ202 engine. The special design of the various
components makes this a particularly lightweight, sturdy and reliable model. If it is installed
correctly and serviced regularly, your engine will last for a long time and meet your
requirements in full.
Avant-garde technology was employed to manufacture this engine which is unique in its kind.
The light alloy cylinder has been treated with Nikasil and is lightweight, reliable and has a
virtually endless life span. The crankshaft is made of nickel-chrome-molybdenum steel
hardened, ground and built to high standards of resistance.
Computer Numerical Control (C.N.C.) equipment and CAD-CAM technology have made it
possible to build ultra-light crankcase. Furthermore, the crankcase incorporates the electric
starter motor.
A 13.8 volt, 180-Watt alternator serves the ignition system and is used to re-charge the starter
battery. Electronic double ignition switching type with variable automatic timing guarantee
reliability, safety and optimum engine performance.
The above features ensure the MZ202 is a complete, lightweight and reliable propulsion system.
Like all high-performance engines, the MZ202 demands care and maintenance. It is vitally
important to use suitable fuel and a good blend of synthetic oil for two-stroke engines with a
50:1 ratio. Proper servicing and an appropriate use are essential requisites.
This manual aims to explain as clearly as possible how to install and get the best out of your
engine.

IMPORTANT SAFETY TIPS
Safety is everybody’s concern. We set out here below an incomplete list of safety precautions to
be taken when using the MZ202. It would be impossible to list all the circumstances, which
may occur when you use this engine, but by being aware of the potential dangers, you will also
reduce some of the risks involved with the use of this engine.
Nonetheless, here is some useful advice
- Never mix fuel in a closed environment where the vapours could cause an explosion.
- Ensure all the engine controls are fully functioning and that you are able to locate the STARTSTOP switch. Make sure you can activate all the controls easily and that you can therefore use
them instinctively and without hesitation.
- Never re-fuel if there is a chance of the fuel dripping onto the hot engine. Use only approved
containers and ensure you comply with the relevant safety regulations when transporting fuel.
- Before each use, check the engine’s mounting points, propulsion components, fuel lines,
wiring and fuel and air filters.
- Use only a clean fuel/oil mixture immediately before using the engine. Check the intake and
exhaust ports. When not in use, protect the engine to prevent impurities from entering the fuel
lines or the fuel itself. Ensure everything is correctly done before starting the engine.
- The engine must be always serviced regularly in order to foresee engine failure at all times.
- Never run the engine on the ground when the propeller is rotating unless the aircraft is located
in an area where you can check that nothing and no-one can access the danger zone.
- Never abandon your aircraft with the engine running.
- If the engine behaves unpredictably, keep a written record. In the event of any problems, do
not take to the air before solving the problem and make a record in the engine logbook.

OIL AND FUEL
Whichever brand of oil and fuel you use, please read the following which will help you keep the
engine in perfect running order.
• The presence of impurities in the fuel is the main cause of engine failure. To prevent the fuel
from being contaminated, it is necessary to take care from the beginning, because the
potential risk increases if impurities enter the fuel tank. Always use a clean fuel container
that complies with safety standards. Always filter the fuel when you fill or change the
container.Do not fill the container to the brim; never forget that fuel may increase in volume.
• Do not use fuel/oil mixtures which have been stored for a long time or which have been
exposed to sunlight in a translucent container. Mix the fuel and oil thoroughly before filling
the fuel tank because there is a risk of the two liquids separating in time.
• Choose the same type and brand of oil and stick to it unless it causes problems. By doing so,
you will get to know the product well and you will be able to assess whether it suits your
engine. If you change the type of oil frequently and your engine has problems, you will never
know which type of oil is responsible for any problems you may have.
• It is extremely important to avoid switching from a synthetic oil to a mineral based oil. The
two types are not always compatible and, if mixed, it is possible that a film may form and
obstruct the engine’s components or cause other problems. As a rule of thumb, 20% of cases
where the user has switched from a synthetic oil to a mineral based oil has resulted in
problems with the engine.
• If the engine has been installed inverted (with the spark plug pointing downwards), choose an
oil that leaves few carbon deposits. Oil deposits tend to build up in the lowest parts, for
example, in the spark plug cavity. If these deposits do not burn during normal use, the spark
plug is fouled and this may result in self-ignition. Manufacturers of top brand lubricants
guarantee the quality of their products.
Oil specifications:: synthetic oil for two-stroke engines: 50 : 1 ratio (Castrol TTS
recommended)
Fuel specifications: the octane rating should be minimum: R.O.N.93 or more.

How to prepare your Fuel/Oil Mixture
A good method for preparing the fuel/oil mixture could prevent a good deal of problems. By
adopting the same method every time, the preparation will become an automatic process that
will simplify matters.
Always use a clean approved container: make sure it is also free of condensation and that you
know the exact capacity.
1. To dilute the oil more easily, pour a small amount of fuel into the container.
2. Pour in the required amount of oil. Shake slowly to mix the oil and fuel.
3. Add sufficient fuel to obtain the prescribed fuel/oil mixture. If you use a filter at this stage,
it should have a very fine mesh in order to filter any water or foreign particles.
4. Screw the lid back onto the container and shake vigorously. Pour the fuel/oil mixture
into the fuel tank of your aircraft. Use a funnel with a filter that is fine enough to prevent
any impurities from entering the fuel tank whilst allowing the oil to pass through.
PRE-START PROCEDURES
Before starting up the engine for the first time, carry out a general inspection, checking in
particular:
-
The carburetor and fuel feed circuit are securely installed.
Check the vacuum pressure tubing between the crankcase inlet and fuel pump, if you have a
Bing carburetor, or the base of the carburetor if you have a Tillotson model.
Check the condition of the electric cables and that the spark plug’s high tension lead has
been fitted correctly.
Check that the two black cables going from the engine shut-off control to the switch have
been connected correctly
Ensure the rubber engine mounts are properly installed and that the locking bolts have been
tightened sufficiently.
Check the gear box and all bolts, nuts on the gear box.
Never run the engine without the propeller; this is particularly important for the free air
model.
Ensure the propeller and locking bolts are in good condition. Check that the propeller is
suitable for the engine as well as the direction of rotation is correct.
10
STARTING UP ENGINE for the FIRST TIME AND BREAK-IN
The engine must be installed and a properly loaded, which means a propeller of the correct
rotation matched for max engine RPM. Also insure that the airplane is properly anchor or tied
to a strong a suitable anchor which will allow full engine run-up.
There are two steps which have to be followed to insure proper engine break-in occurs.
However during both steps insure that the temperature of the cylinder head never exceeds
260°C or 500 F. If during the break-in procedure you feel you are going to exceed the max
cylinder head temperature as per above, interrupt the run, cool down engine at idle for a
minimum of 1 minute and continue where you interrupted the run. During the break-in
procedure, it is particularly dangerous to increase the ratio of the fuel/oil mixture. An excessive
amount of oil will cancel the benefits of the break-in procedure of this engine.
STEP ONE
Step one is a
preliminary engine
run-up to insure that
the engine is
installed correctly
and that all systems
are working
correctly. After
completing Step one
insure all hoses are
not leaking and
cables are fastened
securely.(All time
lengths are minutes).

Now that you have completed step one, Step two is to increase the revolutions of the engine
in increments of 1000 rpm every five seconds up to full throttle and maintain full throttle
for one full minute. During this time monitor the EGT (max 1250F) and CHT (max 500F)
then reduce the rpm in increments of 1000 rpm every ten seconds down to idle. This
concludes the break in period.
This engine is built with a ceramic coated cylinder lining and does not require extensive
break-in time. However, it is recommended for the first two hours of use to avoid
prolonged full throttle.
Best performance of this engine will be attained after the first ten hours of use.
Any irregularities in the engine speed may be caused by a badly adjusted carburettor.
After the first hour of run time is complete, and engine is cooled down the cylinder head bolts
must be re-torqued. And check that all other bolts are tightly fastened in accordance with the
torque settings given in the table above. (Engine must be cool)
11
FINAL CHECK
After having inspected all the bolts, there is one final and extremely important component to be
checked: the spark plug. The spark plugs are a sufficiently reliable indication of the carburetor.
Remove the spark plugs and check the colour of the ceramic insulator at the electrode end. If it
has turned a mid-brown colour, the carburetor has been adjusted correctly. Conversely, if it has
turned black or dark brown, the fuel is too rich. If the ceramic is a light brown or sand colour, it
means the fuel is too lean.
Adjust the carburetor accordingly (see ADJUSTING THE CARBURETOR)
Remember that an excessively rich blend will not cause any immediate problems to the engine
except that carbon deposits will form prematurely. Too weak or lean a blend, however, may
cause irreversible damage to the cylinder and piston.
The engine is now ready to be used as intended.
START UP PROCEDURE
Ensure the contact is on “start” and that you are able to disconnect the circuit immediately, if
necessary. Allow fuel to enter the fuel lines and carburetor by using your plunger primer.
Adjust the throttle position about 20% , Press the starter button until the engine starts (press no
more than 4 to 5 times, taking care not to overheat the starter motor).
After starting the engine, reduce the throttle gradually and disengage the starter as soon as
possible (prolonged use of the starter may damage the motor).
If the engine does not start, check the spark plug caps are secure and that the switch is on
“start”. If nothing still happens, remove and inspect the spark plugs.
If the spark plug is damp, the engine is flooded. Remove the spark plugs, disengage the
ignition and use the starter to crank the engine to discharge any excess fuel in the cylinders.
Replace the spark plugs after having dried them and repeat the starting procedure.
HOW TO USE THE ENGINE
Switch on the engine following the start up instructions.
Wait until the head temperature reaches around 100°C (212 °F), at this point you can use the
engine up to full power checking that the CHT does not go over 260°C (500°F).
When you reduce the RPM, it is normal that CHT may increase a bit for a few seconds in order
to dissipate normal internal temperatures.
12
The air cooled engine is different from the liquid cooled engines in that the CHT temperature will
fluctuate so it is very important to monitor the CHT temperature at all times.
ADJUSTING THE CARBURETOR
Choke and idle adjustment.
1- Choke adjustment.
Before adjusting the idle, ensure that the choke screw is adjusted correctly. This must be
done on a warm engine; the screw is located to the left of the idling mixture adjusting screw in
the main body of the carburetor.
• Switch off the engine and twist the air screw all the way (without applying excess force) then
loosen by turning out the screw (1½). Turns.
• Start the engine, adjust the idler screw so the engine is running at the same speed or faster and
adjust accordingly.
• To do so, turn the air screw slowly in the appropriate direction; this operation should only be
attempted with the engine mounted on a test stand or by trial and error with the engine
switched off, due to the proximity of the propeller.
• It may be necessary to give the screw a ½ turn more or less than the prescribed amount.
2- Idle adjustment.
The minimum number of revs is 1500 rpm. If the idle is not adjusted correctly, the engine
will run irregularly. To adjust, turn the large, external screw in or out accordingly.
Throttle cable
- Once the throttle cable has been fitted, adjust the freeplay between the carburetor and the
throttle lever by acting on the tensioning device.
- Set the throttle lever to minimum.
- Check that the carburetor slide is free to move and that the cable sheath has less than 1 mm of
freeplay (check by pulling the sheath). If necessary, adjust the cable adjusting nuts to achieve the
proper end play.
- Check that the two carburettors open at the same time. It is advisable at this time to sycro-nize
your carburetor use an appropriate carb syc tool.
Choke cable.
The choke cable should have 2-3 mm of freeplay so that the slide is completely free when the
choke is not in use. Adjust by acting on the relative tensioning device.
13
STOP PROCEDURE
Before switching off the engine, maintain a minimum 2000-2500 RPM this will allow a cool
down period and allow that the CHT temperatures to reduce to 150 °C (302°F), then reduce the
throttle to minimum, wait a few seconds, and then shut down the engine. If you follow this
procedure during each engine shut down this will help your engine TBO.
THE GEAR DRIVE
Function of the gear drive
Two-stroke engines are designed in such a way as to generate full power at a high number of revs,
namely, 6000 rpm or higher. At these speeds, the performance of the propeller would be
unsatisfactory on account of its small diameter and would produce an unacceptable amount of
aerodynamic noise on account of the speed of rotation.
The only way of reducing the noise and boosting performance is to fit a gear reducer between the
engine and the propeller
Choosing the right reduction.
This engine is sold with mechanical gear reduction which includes helical gears. We choose this
type of gear for the minimum noise it makes and for the power it can give in a compact size. Our
gear reduction also includes a centrifugal clutch. This combination helps rid any misalignment
and therefore aid in reducing vibration. Further more the clutch reduces the dangerous torsion
movements to the crankshaft during the start-up procedure.
At start-up the propeller is able to free wheel and becomes engaged only when the RPM of the
engine reaches in excess of 1900-2100 RPM per minutes. The gear couple works in an oil bath
therefore check the level of the oil and change the oil after the firsts 5 hours of work. And every
200 hours thereafter. Use only high quality gear oil SAE-90 or SAE 80-120.
The level is up to the lower front plug.
14
TROUBLE SHOOTING
Whatever model you choose, the engine will only function if:
- good spark is produced
- and you have proper air/fuel mix.
Often, the majority of problems arise when one of the above conditions is lacking. Get organised
and follow a strict procedure in order to identify the problem. Finding the problem must be a
logical process. Below is a brief trouble-shooting guide.
1. THE ENGINE WON’T START!

supplying too much fuel when starting up
the engine.
Turn the switch to ON.
Open the valve, clean or replace the filter and
check the fuel lines for any leaks.
Re-fuel.
Repeat the process, following the instructions
carefully.
Remove and clean the spark plugs, run the
engine using the electric starter with the
throttle wide open for 5 seconds then replace
the spark plugs.
Dry the spark plug carefully.
The spark plug is damp on account of
excessive condensation.
The spark plug electrodes are further apart
than the recommended distance.
The electrodes are worn away.
The spark plug is dirty (oil and lead
deposits on the insulator).

WARNING
The engine is supplied with a preassembled wiring harness.
Ensure the battery cables are securely soldered to the terminals.
Bad connections will lead to wire over-heating and irreversible damage to the battery. If you
wish to be able to disconnect the battery, cable connectors of the right size may be used.
Remember that the battery generates 700amps if a short circuit occurs.
When connecting the battery and start-up motor, always ensure the gauge of the cables is
adequate; if the cables used are too small, this could lead to a drop in voltage which will make it
more difficult to start the motor and cause the cables to over-heat and melt.
