2.12. Fuel pump

The fuel pump functions due to the alternating underpressure and overpressure in the crankcase
and sucks fuel from the fuel tank via the fuel pump into the carburetor. In the suction side of the
fuel pump (between fuel tank and fuel pump) a fuel filter is installed to prevent contamination of the
fuel pump and carburetor.

2.13. Centrifugal clutch

The engine is equipped with a centrifugal clutch operating in an oil bath. This clutch separates the
engine from the gearbox at less than 2.500 r.p.m. Only at an engine speed of approx. 4.000 r.p.m.
the centrifugal clutch is completely engaged.

2.14. Overload clutch
