Suction head in the fuel tank
The fuel filler (4) of the suction head is used to filler the fuel required by the
–
carburetor.
A periodical visual inspection of the fuel filter is to be conducted. For that
–
purpose open the tank cap, use a wire hook and pull out the suction head
through the tank opening. Filters found to have hardened, been polluted or
clogged up are to be replaced.
Insufficient fuel supply can result in the admissible maximum speed being
–
exceeded. It is therefore important to replace the fuel filter at least quarterly to
ensure satisfactory fuel supply to the carburetor.

–
If it is clogged by carbon deposits, carefully scratch the deposits out with a
–
suitable tool.
