Refitting
6 Refit in the reverse order to removal.
Adjustment
7 Adjust the cable, by selecting
appropriate position of the spring clip behind
the cable outer bush, to give a small amount
of free play in the inner cable when the pedal
is released. On 1.3 litre models with 13NB
engine, make sure that with the choke control
pushed fully home there is a small clearance
between the fast idle adjuster screw and the
choke cam plate (see illustration).
9 Accelerator pedal - removal
and refitting
Removal
1 If necessary, remove the under-dash trim
on the driver's side to improve access.
2 Disconnect the accelerator cable from the
pedal, as described in Section 8.
3 Prise the spring clip off the end of the
accelerator pivot. Remove
recovering any spacers, washers, bushes etc,
and unhooking the pedal return spring.
Refitting
4 Refit in the reverse order to removal. Adjust
the accelerator cable if necessary on
completion, as described in Section 8.
10 Choke cable - removal,
refitting and adjustment
Removal
1 Disconnect the battery earth lead.
2 Tap out the small pin which secures the
choke control knob to the cable end fitting.
Unscrew and remove the knob.
3 Undo the retaining ring or nut which
secures the choke control to the facia. Push
the control into the facia and disconnect the
warning light switch (when fitted).
4 Remove the air cleaner, as described in
Section 3.
5 Disconnect the choke inner and outer cable
from the carburettor (see illustration). On
some carburettors the inner cable is secured

7 Refit in the reverse order to removal,
adjusting the cable as follows.
Adjustment
8 Adjust the positions of the inner and outer
cables at the carburettor so that, with the
control knob pushed home, there is a small
amount of slack in the inner cable. Secure the
cable in position then operate the choke
control knob and check that the choke linkage
opens fully.

11 Carburettor - description

1 Several types and makes of carburettor are
fitted to the vehicles covered by this manual.
All are of the downdraught type.
2 The 32 TL carburettor fitted to the 1.2 engine
the pedal,
is a fixed jet, single barrel instrument. The 35
PDSI and 1B1 fitted to low compression
versions of the 1.3 engine are similar.
3 The 2E3 carburettor fitted to normal
compression versions of the 1.3 engine is a
fixed jet, twin barrel instrument. Opening of
the throttle valves is sequential; the primary
throttle valve is opened mechanically, but the
secondary throttle valve is opened by vacuum
developed in both venturis. Primary and
secondary transition systems, and a part load

enrichment valve, ensure efficient operation
under all speed and load conditions.
4 The GM Varajet ll carburettor fitted to 1.6
models is also a twin barrel type, but the main
fuel jet is controlled by a tapered needle valve.
The design is well proven and has been used
on several earlier models.
5 All carburettors have a bypass system for
providing idle mixture, and an accelerator
pump for mixture enrichment when the
throttle is opened rapidly.
6 When an automatic choke is fitted, the
choke cover is heated electrically when the
engine is running; as the cover warms up, the
choke is released. On the 2E3 carburettor the
choke cover is also heated by engine coolant.
Both types of automatic choke need to be
'primed' by depressing and releasing the
accelerator pedal before starting the engine
from cold.
Note: Under normal operating conditions only
the carburettor idle adjustments described in
Chapter 1 will need attention. Checking and
adjustment of the following settings is not a
routine operation and should only be
necessary after carburettor overhaul or if the
operation of the carburettor is suspect.
Idle speed and mixture
1 Refer to Chapter 1.
Fast idle
2 This operation may be carried out with the
carburettor installed or removed. If the
carburettor is removed, rotate the choke
linkage on the side of the carburettor until the
linkage arm is against its stop and the choke
valve is fully closed.
3 With the linkage held in this position a small
drill bit, of diameter equal to the fast idle valve
gap given in the Specifications, should just
slide between the throttle valve and the
carburettor barrel (see illustration).
4 If adjustment is necessary slacken the
locknut on the fast idle adjusting screw (see
illustration) and turn the screw as necessary
to achieve the specified setting. Tighten the
locknut after adjustment.
