Fuel system
Remove the pump diaphragm.
Check the diaphragm for damage.
Remove the fuel screen and clean it or
attach a new one.
Remove the main jet.
Remove the bolt holding the cover over
the pump diaphragm.
Lift off the cover (A), the gasket (B) and
the diaphragm (C).
Check the diaphragm for damage to the
valve tongues. If the valve tongues are
bent, the pump will not function in a satis-
factory manner.
Hold it up to a light as well to discover any
holes in the material.
Carefully remove the fuel screen (D), us-
ing a needle for example. Clean or replace
the fuel screen.
NOTE!
During assembly the pump
diaphragm should lie closest
to the carburettor housing.
The carburettor's jets (H) and (L) can only
be adjusted within a very limited area,
which is dependent on the sleeves (A).
Dismantle the jets with the help of tool 530
03 55-60. The sleeves are similar to each
other, but note how they are placed in the
carburettor housing.
