4.3 Carburetor
Do not remove the nozzle, do not modify it!
It‘s part of the engine, which depends on
the correct operation of the engine.
A suction nozzle is mounted on the carburettor, to which we must ensure a sucient air
supply for the correct operation of the engine, do not cover it!
4.4 Fuel system
It is necessary to connect a hose with fuel supply to the carburettor. A protective plug is atta-
ched to the carburettor fuel tting due to dirt during transport. This plug must be removed
and the gas supply from the model‘s tank connected in its place.
When removing the engine from the model for a long time, it is necessary to ret this plug
to prevent the carburettor from drying out and sticking the tab of the intake diaphragm.
