washers, and lift the carburettor from the inlet
manifold studs (see illustrations). Recover
the gasket.
Refitting
9Refitting is a reversal of removal, bearing in
mind the following points.
10Ensure that the mating faces of the inlet
manifold and carburettor are clean, and use a
new gasket.
11Ensure that the coolant hoses, fuel hose,
and vacuum pipe are correctly routed and free
from restrictions. If any of the hoses were
originally secured with crimped type clips,
discard these and use new worm drive clips
on refitting.
12On completion, check and if necessary
top-up the coolant level. Check and if
necessary adjust the idle speed and mixture.
Refer to Chapter 1, Sections 15 and 16.
1Proceed as described for the Ford VV
carburettor but note the following.
2On models with an electrically-heated
automatic choke, ignore all references to the
cooling system and coolant hoses.3Not all Weber carburettors are fitted with an
anti-dieselling valve.
4Disconnect all relevant wiring plugs and
vacuum pipes, if necessary noting their
locations for use when refitting.
5Disconnect the link arm from the throttle
linkage instead of disconnecting the throttle
cable.
6The carburettor is secured to the inlet
manifold by four nuts and washers.
Refer to Chapter 1, Sections 15 and 16.
1This procedure does not apply to models
fitted with a carburettor stepper motor, for
which no adjustment is possible.
2Check the idle speed and mixture. The idle
speed must be correct before attempting to
check or adjust the fast idle speed.
3With the engine at normal operating
temperature, and a tachometer connected in
accordance with the manufacturer’s
instructions, proceed as follows.
4Remove the air cleaner.
5Partially open the throttle, hold the choke
plate(s) fully closed, then release the throttle
so that on 1.6 litre models the fast idle
adjustment screw rests on the third (middle)
step of the fast idle cam (see illustration)and
on 2.0 litre models the fast idle adjustment
screw rests on the highest step of the fast idle
cam (see illustration).
6Release the choke plate(s), checking that
it/they remain(s) fully open; if not, the
automatic choke mechanism is faulty, or the
engine is not at normal operating temperature.
7Without touching the throttle pedal, start
the engine and check that the fast idle speed
is as specified. If adjustment is necessary,
turn the fast idle adjustment screw until the
correct speed is obtained.
8On completion of adjustment, stop the
engine and disconnect the tachometer, then
refit the air cleaner.1Proceed as described for the Ford VV
carburettor but note the following.
2The Pierburg carburettor is not fitted with
an anti-dieselling valve.
3Disconnect all relevant wiring plugs and
vacuum pipes, if necessary noting their
locations as an aid to refitting.
4Disconnect the throttle arm from the throttle
lever by removing the retaining clip instead of
disconnecting the cable (see illustration).
5The carburettor is secured to the inlet
manifold by three Torx type screws (see
illustration).
6On CVH models an insulator block is fitted
between the carburettor and the inlet manifold
in place of a gasket. There is no need to
renew the insulator block on refitting.
