We advise you to mount the tachometer, which facilitates both evaluating the engine’s
state and basic adjustments. It also has the hour meter.
5.5 Regulating the carburetor during the run-in time.
Before sale every carburetor gets its default, factory settings.
If it works well, 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.
During the run-in time you might feel slight and irregular vibrations when the engine is
below 4000 rpm. It is usually caused by too rich minimum speed mixture (the L screw) and
it usually happens when the surrounding temperature is too high. The similar symptom
appears when the space between the spark plug electrodes is too wide. The difference is
that when the problem is a too rich mixture on minimum speed, the symptom disappears
when the speed is increased, and when the electrodes are too far away or the spark plug is
damaged those symptoms increase along with the speed. This can be prevented by leaning
the mixture slightly by using the L screw (vertical screw with head for flat-blade
screwdriver). You must tighten the screw once, for 5’ clockwise and check how the engine
works. Then, you must perform the test flight with the spark plug check-up.
During the run-in time you should avoid changing high-speed mixture composition (the H
screw) 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.
Each newly purchased spark plug has about 1mm space between the
electrodes. You must necessarily reduce it to 0,5mm.
NEVER START THE ENGINE WITHOUT MOUNTING THE PROPELLER. IF THE
ENGINE STARTS WORKING WITHOUT THE BALLAST IT COULD CAUSE IMMEDIATE
AND VERY SERIOUS DAMAGES TO ENGINE.
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.
The Paramotor with the OCTAGON 190 engine is to be used with 125cm or 130cm
propellers.
Using other propellers is not recommended. For instance, too „ballasted” ones might lead to
accelerated engine wear. In turn, too „light” propellers might lead to exceeding the
maximum propeller speed limit, overheating and damage of the engine mechanical parts.
Damages caused by using inadequate propellers are not covered by the warranty.
