Separating gasket and diaphragm
Note: The diaphragm and gasket
often stick to the cover or
carburetor body. If this is the
case, take particular care when
separating them.
- If the fuel strainer in the
pump side of the carburetor
body is dirty, use a scriber to
remove it and then clean it.
Important: If the fuel strainer is
damaged, fit a new one.
In such a case the fuel pickup
body should also be inspected
and replaced if necessary - see
10.7.
- To disassemble the carburetor,
take out the screws of the
metering chamber end cover
and lift away the cover.
- Remove the metering
diaphragm and gasket from
the carburetor body or the
cover.
- Carefully separate the
diaphragm and gasket.
Note: The diaphragms are the
most delicate parts of the
carburetor. They are subjected to
continuous alternating stresses
and the material eventually shows
signs of fatigue, i.e. the
diaphragms distort and swell.
Check and replace if necessary.
