away the top cover with float.
4Refer to Section 9 paragraphs 4 and 5 for
details of removal of the fuel inlet needle
valve.
Float adjustment
5Invert the carburettor cover so that theweight of the floats depresses the ball of the
needle valve.
6Measure the distance between the float and
the surface of the cover gasket. This should
be between 6.5 and 7.5 mm (0.26 and 0.30 in).
If adjustment is required, change the
thickness of the needle valve washer or
carefully bend the float arm.
Accelerator pump
7Refer to Section 10, paragraphs 6 and 7.
The total volume of fuel collected should be
between 7.5 and 9.5 cc. If the volume of fuel
is incorrect, release the locknut and turn the
adjuster screw on the pump lever then re-test
the volume ejected.
Fast idle
8Operate the choke control lever to close the
choke valve plate. The gap between the edge
of the primary throttle valve plate and the

(Fig. 3.32) between the edge of the choke
valve plate and the wall of the carburettor
throat of between 4.75 and 5.25 mm (0.187
and 0.207 in).
11Where adjustment is required, release the
locknut and turn the screw on the lean out
valve.
16 Economy meter
1This device is fitted to ES (energy saving)
models. It is essentially a vacuum gauge to
advise the driver with regard to economical
throttle opening related to engine and road
speed. The point of change to a higher gear
can also be deduced from this gauge. The
latter facility is provided by an LED (light
emitting diode).

1The socket type cable end fitting is
detached from the carburettor throttle lever
simply by prising it off the ball stud.
2Adjustment can be carried out by releasing
the locknut and turning the end fitting. With
the accelerator pedal fully depressed, check
that full throttle can be obtained at the
carburettor.
3To renew the cable, prise off the end fitting
from the carburettor throttle lever.
4Slip the cable sleeve from its retaining
bracket (photo).
5Working inside the car under the facia
panel, slip the cable from the fork at the top of
the accelerator pedal arm (photo). 6Withdraw the cable through the engine
compartment bulkhead.
7Fit the new cable by reversing the removal
operations, adjust as described in para-
graph 2.
18 Choke control cable-
removal and refitting
2
1Remove the air cleaner.
2Release the choke outer cable clamp and
the inner cable from the swivel on the choke
control lever (photo).
3The choke control is of lever type. To
remove it, extract its hinge screw, accessible
when the lever is pulled upwards (photo).
4Withdraw the choke cable assembly until
the inner cable can be released from the handcontrol lever and the choke warning lamp lead
unplugged.
5Withdraw the cable assembly through the
engine compartment rear bulkhead.
6Fit the new cable by reversing the removal
operations. Before tightening the inner cable
pinch screw at the carburettor, hold the choke
valve plate open and pull the control lever out
2.0 or 3.0 mm, then tighten the screw. This
will provide just enough free movement to
ensure that when the control is pushed fully in
the choke valve plate will remain fully open
even with engine movement slightly stretching
the cable.
19 Manifolds and exhaust
system
1
1The intake manifold on 903 cc engines is
integral with the cylinder head.
2On the other engines, the intake and
exhaust manifolds are mounted on the same
side of the cylinder head.
3A hot air collector plate is fitted over the
exhaust manifold from where the air cleaner
draws air when in the winter setting.
4When fitting a manifold, thoroughly clean
the cylinder head and manifold mating
surfaces, use a new gasket and tighten nuts
to the specified torque (photos).
5The exhaust system on 903 cc models is of
single downpipe, single silencer two section
type.

outwards, they rotate the cam relative to the
distributor shaft, and so advance the spark.
The weights are held in position by two
springs and it is the tension of the springs
which is largely responsible for correct spark
advancement.
The vacuum advance is controlled by a
diaphragm capsule connected to the
carburettor venturi. The vacuum pressure
varies according to the throttle valve plate
opening and so adjusts the ignition advance
in accordance with the engine requirements.
Digiplex ignition system
This electronic system eliminates the
mechanical contact breaker and centrifugal
advance mechanism of conventional
distributors and uses an electronic control
unit to provide advance values according to
engine speed and load. No provision is made
for adjustment of the ignition timing.
Information relayed to the control unit is
provided by two magnetic sensors which
monitor engine speed and TDC directly from
the engine crankshaft.
A vacuum sensor in the control unit
converts intake manifold vacuum into an
electric signal.
The control unit selects the optimum
advance angle required and a closed
magnetic circuit resin coil guarantees a spark
owing to the low primary winding resistance.
Five hundred and twelve advance values
are stored in the control unit memory to suit
any combination of engine operating
conditions.
No maintenance is required to the
distributor used on this system.
Distributor drive
The mechanical breaker type distributor on
903 cc engines and the Digiplex type
distributor on 903 cc ES engines are mounted
on the cylinder head and driven from a gear
on the camshaft through a shaft which also
drives the oil pump.
The distributor on 1116 cc and 1301 cc
engines is mounted on the crankcase and is
driven from a gear on the auxiliary shaft as is
also the oil pump.
2 Mechanical contact breaker
- points servicing
3
1At the intervals specified in “Routine
Maintenance”, prise down the clips on the
distributor cap and place the cap with high
tension leads to one side.
2Pull off the rotor.
3Remove the spark shield. Mechanical wear
of the contact breaker reduces the gap.
Electrical wear builds up a “pip” of burned
metal on one of the contacts. This
|prevents the gap being measured for
re-adjustment, and also spoils the electric
circuit.
Ducellier type distributor
4To remove the contact breaker movable
arm, extract the clip and take off the washer
from the top of the pivot post.
5Extract the screw and remove the fixed
contact arm.
6Clean the points by rubbing the surfaces on
a fine abrasive such as an oil stone. The point
surface should be shaped to a gentle convex
curve. All the “pip” burned onto one contact
must be removed. It is not necessary to go on
until all traces of the crater have been
removed from the other. There is enough
metal on the contacts to allow this to be done
once. At alternate services, fit new points.
Wash debris off cleaned points and
preservatives off new ones.
7Now the distributor should be lubricated.
This lubrication is important for the correct
mechanical function of the distributor, but
excess lubrication will ruin the electrical
circuits, and give difficult starting.
8Whilst the contact breaker is off, squirt
some engine oil into the bottom part of the
distributor, onto the centrifugal advance
mechanism below the plate.
9Wet with oil the felt pad on the top of the
distributor spindle, normally covered by the
rotor arm.
10Put just a drip of oil on the pivot for the
moving contact.11Smear a little general purpose grease
onto the cam, and the heel of the moving
contact breaker.
12Refit the contact points and then set the
gap in the following way.
13Turn the crankshaft by applying a spanner
to the pulley nut or by jacking up a front
wheel, engaging top gear and turning the
roadwheel in the forward direction of
travel. Keep turning until the plastic
heel of the movable contact arm is on the
high point of a cam lobe on the distributor
shaft.
14Set the points gap by moving the fixed
contact arm until the specified feeler blades
are a sliding fit. Tighten the fixed contact arm
screw.
15Check the contact end of the rotor arm.
Remove any slightly burnt deposits using fine
abrasive paper. Severe erosion will
necessitate renewal of the rotor.
16Wipe out the distributor cap and check for
cracks or eroded contacts (photo). Renew if
evident or if the carbon brush is worn.
17Refit the spark shield, rotor and distributor
cap.
18Setting the contact breaker gap with a
feeler blade must be regarded as a means of
ensuring that the engine will start. For
optimum engine performance, the dwell angle
must be checked and adjusted as described
in Section 3.
Marelli type distributor
19Open the points with a finger nail and
inspect their condition. If they are badly
eroded or burned, then they must be
renewed. The contact points can only be
renewed complete with carrier plate as an
assembly.
20Release the low tension leads from the
terminals on the distributor body (photo).
21Extract the screws which hold the vacuum
advance capsule to the distributor body. Tilt
the capsule and release its link rod from the
contact breaker carrier plate (photo).
22Prise out the E-clip from the breaker
carrier and then withdraw the contact
assembly from the top of the distributor shaft.

Note the washers above and below the
contact assembly (photos).
23Fit the new contact assembly by reversing
the removal operations.
24Although the points gap is normally set in
production, check it using feeler blades when
the plastic heel of the movable arm is on a
high point of the shaft cam. Adjust if
necessary by inserting an Allen key (3.0 mm)
into the socket-headed adjuster screw.
25Carry out the operations described in
paragraphs 14 to 17 in this Section.
3 Dwell angle- checking
3
The dwell angle is the number of degrees
through which the distributor cam turns
between the instants of closure and opening
of the contact breaker points.
1Connect a dwell meter in accordance with
the maker’s instruction. The type of meter that
operates with the engine running is to be
preferred; any variation in contact breaker
gap, caused by wear in the distributor shaft or
bushes, or the height of the distributor cam
peaks, is evened out when using this.
2The correct dwell angle is given in the
Specifications at the beginning of this
Chapter. If the angle is too large, increase the
contact points gap. If the angle is too small,
reduce the points gap. Only very slight
adjustments should be made to the gap
before re-checking.3On Ducellier distributors, adjustment of the
dwell angle can only be carried out by
switching off the ignition, removing the
distributor cap, rotor and spark shield and
adjusting the points gap.
4Re-check once the engine is running.
Adjustment may have to be carried out
several times to obtain the correct dwell
angle.
5On Marelli distributors, adjustment of the
points gap (dwell angle) is carried out with the
engine running by inserting a 3.0 mm Allen
key in the hole provided in the distributor
body.
6Always check and adjust the dwell angle
before timing the ignition as described in
Section 4.
4 Ignition timing
3
1Timing the ignition on engines with
mechanical breaker distributors is carried out
in the following way.
2Disconnect the vacuum hose from the
distributor diaphragm capsule (photo).
3Have the engine at normal operating
temperature and idling with a stroboscope
connected in accordance with the
manufacturer’s instructions.
4Point the stroboscope at the timing marks
on the flywheel and the index on the aperture
on the flywheel housing. The mark on the
flywheel should be opposite to the BTDC
mark on the index specified for your particular
engine. Alternatively, use the notch on the
crankshaft pulley and the marks on the timing
belt cover (photo), but this will necessitate
removal of the wheel arch shield.
5If the marks are not in alignment, release
the distributor clamp plate and turn the
distributor gently until they are (photo).
6Tighten the clamp plate nut, switch off the
ignition, reconnect the vacuum hose and
remove the stroboscope.
7If there is any difficulty in seeing the timing
marks clearly, highlight them by painting with
quick-drying white paint.

this type is used and the engine is in good
condition, the spark plugs should not need
attention between scheduled replacement
intervals. Spark plug cleaning is rarely
necessary and should not be attempted unless
specialised equipment is available as damage
can easily be caused to the firing ends.
2At the specified intervals, the plugs should
be renewed. The condition of the spark plug
will also tell much about the overall condition
of the engine.
3If the insulator nose of the spark plug is
clean and white, with no deposits, this is
indicative of a weak mixture, or too hot a plug.
(A hot plug transfers heat away from the
electrode slowly - a cold plug transfers it away
quickly.)
4If the tip of the insulator nose is covered
with sooty black deposits, then this is
indicative that the mixture is too rich. Should
the plug be black and oily, then it is likely that
the engine is fairly worn, as well as the mixture
being too rich.
5The spark plug gap is of considerable
importance, as, if it is too large or too small
the size of the spark and its efficiency will be
seriously impaired. The spark plug gap should
be set to the gap shown in the Specifications
for the best results.
6To set it, measure the gap with a feeler
gauge, and then bend open, or close, the
outer plug electrode until the correct gap is
achieved. The centre electrode should never
be bent as this may crack the insulation and
cause plug failure, if nothing worse.
7When fitting new plugs, check that the plug
seats in the cylinder head are quite clean.
Refit the leads from the distributor in the
correct firing order, which is 1-3-4-2; No 1cylinder being the one nearest the flywheel
housing (903 cc) or timing belt (1116 or
1301 cc). The distributor cap is marked with
the HT lead numbers to avoid any confusion.
Simply connect the correctly numbered lead
to its respective spark plug terminal (photo).

4Pull the two leads from the switch.
5Turn the ignition key to MAR.
6Using a screwdriver depress the retaining
tabs (1) (Fig. 4.16) and release the ignition
switch.
7Set the switch cam (2) so that the notches
(3) are in alignment.
8Insert the switch into the steering lock and
engage the retaining tabs.
9Turn the ignition key to STOP and connect
the two leads.
10Reconnect the battery and refit the
steering wheel, switch and shrouds.
11Removal and refitting of the steeringcolumn lock is described in Chapter 10.
Note: The ignition key is removable when set
to the STOP position and all electrical circuits
will be off. If the interlock button is pressed,
the key can be turned to the PARK position in
order that the parking lamps can be left on
and the steering lock engaged, but the key
can be withdrawn.

It’s often difficult to insert spark plugs
into their holes without cross-threading
them. To avoid this possibility, fit a
short piece of rubber hose over the end
of the spark plug. The flexible hose
acts as a universal joint, to help align
the plug with the plug hole. Should the
plug begin to cross-thread, the hose
will slip on the spark plug, preventing
thread damage.

1 General description
The electrical system is of 12 volt negative
earth type and employs a belt-driven
alternator and a pre-engaged type starter
motor.
The models in the range are all adequately
equipped with electrical accessories, while SX
versions also have power windows and
centralised door locking plus a check control
system (Section 34).
2 Battery- inspection, charging,
removal and refitting
2
1The battery is of maintenance-free type and
under normal circumstances, no topping up
will be required, but regularly check that the
electrolyte level is between the minimum and
maximum lines on the translucent battery
casing.
2If the electrolyte level does drop below theminimum line, suspect a leak in the battery
casing or that the alternator is overcharging. If
the latter is the case, rectify the alternator fault
and then prise out the two rectangular plugs
from the top of the battery and top up with
distilled or purified water.
3Always keep the battery terminals clean
and smear them with petroleum jelly to
prevent corrosion.
4The battery will normally be kept fully
charged by the alternator, but it is possible for
the battery to become discharged if the daily
mileage is very low with much use being
made of the starter and electrical accessories.
5When the battery begins to deteriorate with
age it may also require a boost from a mains
charger.
6Disconnect both battery leads before
connecting the mains charger. 7To remove the battery from the car, first
disconnect the leads from the battery
terminals (earth first) and then unscrew the
securing clamp from the casing projection at
the base of the casing (photo).
8Lift the battery from its mounting platform.
Refitting is a reversal of removal. Reconnect
the earth cable last.

If battery terminal corrosion
has occurred, it may be
neutralised by applying
sodium bicarbonate or
household ammonia.
