Opel Kadett User Manual

Note: In the rare event of a complete
carburettor overhaul being necessary, it may
prove more economical to renew the
carburettor as a complete unit. Check the price
and availability of a replacement carburettor
and of its component parts before starting
work; note that most sealing washers, screws
and gaskets are available in kits, as are some of
the major sub-assemblies. In most cases it will
be sufficient to dismantle the carburettor and
to clean the jets and passages.
1 Remove the carburettor from the engine.
2 Detach the vacuum unit pull-down hose
from the throttle body housing.
3 Remove the four retaining screws and
separate the top cover from the carburettor
body (see illustration).
4 Remove the idle speed and mixture
adjustment screws, and the idle cut-off valve
or plug (see illustration).
5 If necessary the throttle valve lever, cam
plate and return spring can be removed after
removal of the shaft nut (see illustration). As
they are removed, note their relative positions.
6 Remove the two retaining screws and lift off
the part-load enrichment device cover, spring
and diaphragm (see illustration).
7 Remove the accelerator pump collar, piston
and spring (see illustrations).
8 Pull the accelerator pump delivery tube out
of the carburettor body (see illustration).
Note the spring and ball.
9 Press out the float pin and remove the float
and needle valve (see illustrations).
10 Unscrew and remove the main jet (see
illustration).
11 Remove the choke thermal and vacuum
units by undoing the three retaining screws.
12 Unscrew and remove the idle fuel/air and
auxiliary fuel/air jets from the carburettor
body, taking note of the location of each (see
illustration).
13 Further dismantling is not recommended.
