A pressure equilibrium must always
prevail between the inside of the
fuel tank and the surrounding
atmosphere to permit troublefree
operation of the carburetor. This is
ensured by the tank vent.
If problems develop in the
carburetor or fuel supply, the tank
vent must always also be tested and
replaced if necessary. Correct
functioning is determined by testing
the fuel tank with negative pressure
via the fuel hose.
– Remove the carburetor,
– Drain the fuel tank.
Note:
Ensure that the fuel is disposed of
correctly and without harming the
environment.
