Regulating The Carburetor During The Run-In Time - Air Conception REVOLUTION 200 Instruction Manual


During the run-in time it is generally recommended to use the engine on differential
speed and not to keep one speed for a long time (e.g. long flight on a steady altitude).

Manipulating gently with the gas throttle during the run-in and acting according to the
guidelines described above will lead to sustained and trouble-free engine running and
significantly prolong the amount of time before the first repair. If the user intentionally does
not follow the guidelines presented above, it will cause the loss of any warranty rights or the
engine's damage. It is important to bear in mind that preserving the engine in the best
shape during further exploration depends on how we handle it in the first hours.
The run-in time for any of our engines is about 10 hours of flight.

The practical way of estimating the length of run-in stage is using up 1 litres bottle of oil.

We advise you to mount a tachometer, which facilitates both evaluating the engine's
state for basic adjustments and serves as an hour meter.

5.5 Regulating the carburetor during the run-in time

Before sale every carburetor is set to default, factory settings.
You only need to regulate the idle speed because it changes together with the changes in
atmospheric pressure (horizontal screw lifting the throttle lever).
After the warm-up, we set speed on 2100-2200 rpm or so that the engine could work
steadily and would not cut out. A tick any lower than 2100 rpm could damage the engine.
During the run-in time you should avoid changing mixture composition (the L and H screws)
even if the spark plug check-up shows that the mixture is too rich. At this time, your priority
is lubricating and preventing the engine from overheating.

Note about sparkplugs:
Space between the electrodes of IW31 and IW34 iridium sparkplugs is NOT to be modified.
Space between the electrodes or other regular sparkplugs is to be reduced from 1 mm to
0.4 mm.
When the engine is hot, the temperature of some exhaust system parts may exceed
300 o C. Touching the engine, even by accident, may cause serious burns.
Your paramotor is to be used with E-props (Electravia) propellers.
Using other propellers is not recommended. For instance, too "ballasted" ones might lead to
accelerated engine wear. Damages caused by using damaged or inadequate propellers are
not covered by the warranty.
