Our 1972 Austin and MG engines ha ve not been designed to operate on lead-freeor clear gasoline s and use of such fuels cannot be recommended as they couldha ve a detrimental effect on engine components, resulting in loss of perform­ance, excess exhaust emissions and , possibly , complete engine failure.

Controls Heater (Fig ..1). A valve controlling the flow of coolant through the heater unitis fitted at the rear of the cylinder head. The valve is opened by turning it in ananti-clockwise direction when heating is required or shut off by turning clockwisewhen the system is to be used for cool air ventilation.

Air flow (Fig. 2). The knob (1) operates a valve in the air intake and controls theflow of air to the car interior. Turn the knob anti-clockwise from the 'OFF'position to open the valve, the valve is fully open when the knob is turned tothe 'ON ' po sition.

Booster. Press the lower end of the switch rocker (2) to boost the air flow.

Usage By varying the settings of the air flow control, opening or closing the air distri­bution doo rs, and utilizing the boo ster blower, a wide range of settings can beobtained for heating, when the heater valve is open, or for ventilating when thevalve is shut, to suit prevailing conditions.

Starting Check that the gear lever is in the neutral position.

If the engine is cold , pull out the mixture control (choke). In extremely cold'conditions it may be necessary to pull the control out to its fullest extent. Lockthe control in the desired position by turning the control knob clockwise .

Switch on the ignition, check that the ignition' warning light glows and that thefuel gauge registers, then operate the starter. NOTE.-After switching the igni­tion on, the fuel gauge needle moves slowly across the scale, taking some 30seconds to reach the true reading. This slow reaction eliminates needle flutter.

As soon as the engine starts, release the ignition key and warm up the engine ata fairly fast speed (see 'Warming up'). Check that the oil pressure gauge isregistering and that the ignition warning light has gone out. Release the mixturecontrol from the locked position and push in the control as soon as the enginewill run evenly without its use.

Starter Do not operate the starter for longer than five to six seconds.

To prevent damage the starter cannot be operated while the engine is running.

If after a reasonable number of attempts the engine should fail to start, switchoff the ignition and investigate the cause. Continued use of the starter when theengine will not start, not only discharges the battery but may also damage thestarter.

The fast idle speed is obtained by pulling the control out tin. (6 mm.) .

Mixture Always use the minimum setting for the shortest possible time .control I I I .As soon as possible after the engine has started, push the contro comp ete y m.(choke)

Running Instructions

Driving the car onto the road while the engine is cold and the mixture (choke)control is partl y pulled out is preferable to allo wing the engine to idle, or runwith the choke pulled out, in the garage or on the driveway prior to moving off.

Ig nition The light should glow when the ignition is switched on , and go out and stay outw arn ing light at all times while the engine is running above normal idling speed . Failure to do

so indicates a fault in the battery charging system. Check that the fan belt iscorrectly tensioned before consulting your Di stributor or Dealer.

O i l pressure The gaugeshould register a pre ssure as soon as the engine is star ted up. Thegauge pressure may rise above 70 lb .jsq . in. (4 '92 kg.jcm.") when the engine is started

from cold and as the oil is circulated and warmed the pressure should then dropto between 40 and 70 lb .jsq. in. (2'81 to 4·92 kg.jcm.") at normal running speedsand to approximately 20 lb .jsq . in. (1'4 kg. jcm.") at idling speed.

Should the gau ge fail to register any pressure, stop the engine immediately andinvestigate the cause. Start by checking the oil level.

Temperature Normal operating temperature is reached when the pointer is in the 'N ' sector.g auge

Run n ing in Th e treatment given to a new car will ha ve an important bearing on its subsequentlife, and engine speeds during this early period must be limited. The follo winginstru ctions should be str ictly adhered to .

During the first 500 miles (800 km .) :

DO NOT exceed 45 m.p.h . (72 km .p.h .).

DO NOT operate at full throttle in any gear.

DO NOT allow the engine to labou r in any gear.

Ta chometer For normal roa d work, and to obtain the most satisfact ory service from yourengine, select the appropriate gear to maintain engine speeds of between 2,000

. and 4,500 r.p.m.

When ma ximum acceleration is requi red upward gear selections should be madewhen the needle reache s the yellow sector (5,500- 6,300 r.p .m.) . Prolonged orexcessive use of the highest engine speeds will tend to shorten the life of theengine.

Should the gauge fail to register any pressure, stop the engine immediately andin vestigate th e ca use . Start hv check ing th e oil level .

Towi ng Should it become necessary to tow the c~r, use the towing eyes pro vided .

The car may be towed for recovery with the ignition steering lock key in the lockat position 'I'. .

Testing brakes The warning light on the fascia panel will glow when the brake pedal is pressedif an excessive. difference in pressure exists between the front and rear hydraulicsystems as a result of a hydraulic failure or extreme lack of adjustment on therear brakes.

To test the warning lamp bulb, elect rical supply, and serviceability of the wiringto the operating valve, press the test -pu sh on the bottom of the lamp mountingplate. The lamp will glow if the electrical system is operating satisfactorily.Release the test-pus h and apply normal foot pressure to the brake pedal; thelamp will remain off if the brakes are func tioning satisfactorily. Check the brakewarning system frequently.

If the warning lamp glows at any time except when the electrical system is beingtested, whether during normal dri ving or when the brakes are being tested asabove, the cau se must be investigated by your Di stributor or Dealer at theearlie st possible opportunity.

Vehicle loading D ue cons ideration must be given to the overall weight carried when h illy loadingthe car. Any loads car ried on a roof rack or downward load from a towinghitch must also be included in the maximum loading.

Towing The towing weight of 1,344 lb. (610 kg.) is the max imum that is permissible.When using bottom gear a gradient of up to 1 in 8 can be ascended while towinga weight not exceeding this figure. It may be necessary to adjust the ma ximumtowing weight to comply with local conditions and regulations. The recommendeddownward load of a trailer or caravan on the towing hitch is 75 to 100 lb . (34to 45 kg.), but thi s may be reduced or exceeded at the discretion of the driver.Any load car ried on the roof or downward load from a towing hitch must alsobe included in the maximum loa ding of the vehicle .

CLEANING

Interior Clean the carpets with a semi-stiff brush or a vacuum cleaner preferably beforewashing the outside of the car. The most satisfactory way to give carpets athorough cleaning is with UNIPART Upholstery Cleaner, diluted one part witheight parts warm water. Apply vigorously with a semi-stiff brush, and removethe surplus with a damp cloth or sponge. Carpets should not be cleaned by the'dry-clean' process. The upholstery and roof lining may be treated with undilutedUNIPART Upholstery Cleaner spread thinly over the surface to be cleaned witha brush or cloth. Leave for five minutes, then wipe off with a moist sponge orcloth.

UNIPART Upholstery Cleaner can be used for cleaning and renovating all theusual upholstery materials, and rubber, but it should not be used on paintedsurfaces.

Body Regular care of the body finish is necessary if the new appearance of the carexterior is to be maintained against the effects of air pollution, rain, and mud.. .Wash the bodywork frequently, using a soft sponge and plenty of water con­taining UNIPART Car Shampoo. Large deposits of mud must be softened withwater before using the sponge. Smears should be removed by a second wash inclean water, and with the sponge if necessary. When dry, clean the surface of thecar with a damp chamois-leather. In addition to the regular maintenance, specialattention is required if the car is driven in extreme conditions such as sea sprayor on salted roads. In these conditions and with other forms of severe contamina­tion an additional washing operation is necessary which should include under­body hosing. Any damaged areas should be immediately covered with paint anda complete repair effected as soon as possible. Before touching-in light scratchesand abrasions with paint, thoroughly clean the surface. Use petrol/white spirit(gasoline/hydrocarbon solvent) to remove spots of grease or tar.

The application of UNIPART Car Polish is all that is required to remove trafficfilm and to ensure the retention of the new appearance.

Bright trim Never use an abrasive on stainless, chromium, aluminium, or plastic bright partsand on no account clean them with metal polish. Remove spots of grease or tarwith petrol/white spirit (gasoline/hydrocarbon solvent) and wash frequentlywith water containing UNIPART Car Shampoo. When the dirt has been removedpolish with a clean dry cloth or chamois-leather until bright. Any slight tarnishfound on stainless or plated components which have not received regular attentionmay be removed with UNIPART Chrome Cleaner. An occasional application oflight mineral oil or grease will help to preserve the finish, particularly duringwinter, when salt may be used on the roads, but these protectives must not beapplied to plastic finishes. ~

COOLING SYSTEM

Expansion The expansion tank collects the coolant displaced by expansion when the enginetank and cap is heated to normal running temperature. The displaced coolant is returned to the

radiator when the system cools. The cap (1) on the expansion tank maintains thepressure in the cooling system to 15 lb./sq . in. maximum when the engine is .running. If the system is hot , protect the hands against escaping steam, turnthe cap anti-clockwise to the stop , wait unti l all pressure has escaped , press downand turn further until the cap can be lifted off.

Checking The coolant level must only be checked when the system is cold. Remove theexpansion tank cap (1) to check the coolant level which must be maintained tothe half-full point of the tank.

Draining To drain the cooling system, stand the ' car on level ground and remove theradiator filler plug (3). Slacken the hose clips and disconnect the bottom hoseat its connection to the radiator. Remove the drain plug (2) on the enginecylinder block .

There is no provision for draining the heater or expansion tank,

Filling Refit the drain plug, and open the heater valve. Fill the system through theradiator filler orifice and fit the filler plug. Top up the coolant on the expansiontank to the half-full point and refit the cap. Run the engine at a fast idle speedfor 30 seconds, stop the engine and top up the system through the radiator filler.

Refit the filler plug and bottom hose and run the engine until normal operatingtemperature is reached . Stop the engine and allow the system to cool then topup the expansion tank to half-full.

IGNITION

Ign iti o n The ignit ion timing is set dynamically to give optimum engine performance withtiming efficient engine emission control. Electronic test equipment must be used to

check the ignition timing setting and the au tomatic advance (see 'GENERALDATA'). Checking and adjustment to the ignition timing setting should becarried out by your Austin MG Dealer control service station.

The dynamic ignition timing must be checked after clean ing, resetting, or renew-ing of the distributo r contacts. '\

Basic tuning data will be found on the Vehicle Emission Control InformationLabel located in the engine compartment. .

Distri butor Cleaning contacts. Inspect the contact points (1) and, if burned, clean with fineFig. 1 emery cloth or fine carborundum stone . Wipe the contacts clean with a fuel-

moistened cloth. Renew pitted or worn points. .

Fitting . Before fitting a new contact set, wipe the points clean with fuel or spirit.Lubricate the pivot post (2) and check that the insulating bush (9) is correctlypositioned below the spring loop. Position the contact set on the distributorplate and lightly tighten the securing screw (6)~ Locate the lead terminals aroundthe insulating bush so that they make contact with the spring and tighten thenut (8). Set the contact gap.

Whenever a new contact set has been fitted, recheck the gap after the first 500miles (800 km.). During this period, the heel of the contact will have bedded inand reduced the gap.

Ignition cables 'The high-tension cables connecting the distributor to the sparking plugs may,(high-tension) after long use, also show signs of perishing; They must then be replaced by the

correct type of ignition cable.

Lubrication. Very lightly smear the pivot post (2) and aro und the cam (3) withgrease. Add a few drops of oil thr ough the hole in the contact breaker plate tolubricate the centrifugal weights and around the screw (5) in the centre of thecam spindle (do not remove this screw' as clearance is prov ided for oil to pass).Avoid over-lubricating. Carefully wipe away all surplus lubricant and see that thecontact breaker points are perfectly clean and dry .

Contact breaker gap. Turn the crankshaft un til the points are fully open. Checkthe contact gap (1) with a feeler gauge (see 'GENERAL DATA') ; the gaugeshould be a sliding fit in the gap.

If the gap varies appreciably from the gauge thickness, slacken the contact platesecuring screw (6) and adjust the gap by inserting a screwdriver in the notchedhole (7) at the end of the plate and turning clockwise to decrease and anti­clockwise to increase the gap . Tighten the securing screw. Turn the crankshaftand recheck the gap. Refit the rotor, wipe the inside of the distributor coverclean and refit.

Contact set renewing. Removing. Remove the nut (8), lift the top insulating bushand both leads from the stud . Rem ove the securing screw (6) with its spring andplain washers, and lift off the one-piece contact set. If removal of the mov ingcontact onl y is required, leave the securing screw (6) in posit ion.

The dynamic ignition timing must be checked after clean ing, resett ing, or renew-ing of the distributor contacts. '\

The spar k plugs should be cleaned, preferably with an air-blast service unit.

Check the plug gaps, and reset if necessary to the recommended gap (see'GENERAL DATA'). To reset, use a special Champion spark plug gauge andsetting tool; move the side electrode , never the centre one .

When refitting the plugs make sure that the washers are not defective in any way.

Screw the plug down by hand as far as possible, then use a spanner for tighteningonly. Always use a tubular box spanner to avoid possible damage to the insulator,and do not under any circumstances use a movable wrench. Never overtighten aplug, but ensure that a good joint is.made between the plug body, washer, andcylinder head . Wipe clean the outside of the plugs before reconnecting the H.T.leads . .

When fitting new spark plugs ensure that only the recommended type andgrade are used (see 'GENERAL DATA').

EMISSION CONTROL SYSTEMS

You and each subsequent owner of the car are urged to make sure that therecommended maintenance procedures are carried out at the intervals specified .In order for the emission controls to continue to fun ction effectively, it is stronglyrecommended that you arrange for regular maintenance inspections to be carriedout by your Austin MG Dealer.

Fuel To prevent air pollution by vapours from the fuel tank and carburetter vent s,Evaporative the control equipment stores the vapour in a charcoal filled cani ster while the

Loss Control engine is stopped and disposes of it via the engine crankcase emission controlsystem when the engine is running.

The Passport to Service pro vides an inspection and maintenance schedule up to50,000 miles or five years whichever first occurs, the period for which federallaw requires that the emission control systems shall continue to function effectively.You should have the maintenance reco rd completed by your Austin MG Dealer(or by other dealer or station equipped to render such service) at the regularmileage intervals indicated in the Schedule. The Handbook and Passport toService should be handed to subsequent purchasers of the vehicle at the time ofsale so that the maintenance instructions are available and that the record ofmaintenance can be continued.

You are also urged to study with care the section covering 'MALFUNCTIONIDENTIFICATION'. Study of this section will be of aid to you in detectingpossible malfunctions of the emission controls so that necessary service measurescan immediately be taken.

Each owner should consult the warranty applicable to this vehicle, found in thePassport to Service, for those provisions applicable to the emission controlsystems. The warranty provides that the manufacturer guarantees to you andeach subsequent purchaser that the emission control systems with which yourcar is equipped conformed at the time of manufacture with applicable regulations,and are free from defects in materials and workmanship which might cau se thevehicle or engine to fail to conform with those regulations.

IMPORTANT

Your attention is particularly drawn to the following:

1. Maintenance and service charges applicable to the emission control system arenot covered by the warranty and are not reimbursable, unless shown to havebeen caused by defects in materials and workmanship covered by the warranty.

2. Our 1972 Au stin and MG engine s have not been designed to operate onlead-free or clear gasoline and use of such fuels cannot be recommended asthey could have a detrimental effect on engine components resulting in lossof performance, excess exhaust emissions and possibly complete enginefailure .

The fuel tank venting is designed to ensure that vapours are vented through thecontrol system even when the car is parked on an inclined surface.

A capacity limiting device in the fuel tank ensures sufficient free capacity isavailable after filling to accommodate fuel which would otherwise be displacedas a result of a high temperature rise. The inclusion of a small separation tankin the vapour line prevents liquid fuel from being carried with the vapour tothe storage canister.

Emission Control Systems

Crankcase The engine crankcase breather outlet incorporates an oil separator flame-trapEmission which is connected by hoses to the controlled depression chamber between the

Control piston and the throttle disc valve of the carburetter(s). Piston blowby fumes aredrawn into the chamber where they combine with the engine inlet charge forcombustion in the engine cylinders in the normal way. Fresh filtered air is suppliedto the engine crankcase through a hose connected between the engine valve rockercover and the charcoal canister of the fuel evaporative emission control system .

Filler caps Both the engine oil filler cap and the fuel tank filler cap are non-venting and forma seal on the filling apertures.

IT IS ESSENTIAL TO THE SATISFACTORY OPERATION OF THEEVAPORATIVE LOSS SYSTEM THAT BOTH CAPS ARE ALWAYSREFITTED CORRECTLY AND TIGHTENED FULLY. A DEFECTIVECAP OR CAP SEAL MUST BE REPLACED

Fig. 2 The emission control components

Filler caps Both the engine oil filler cap and the fuel tank filler cap are non-venting and forma seal on the filling apertures.

Exhaust The main feature of the exhaust emission control system is a combination of theEmission engine modification and air injection techniques and consists of modified

Control carburetters, modified ignition timing, and air injection into the exhaust ports .

The quantity of air-polluting elements in the gases leaving the exhaust pipe isreduced by adding air to the hot gases immediately they leave the combustionchambers of the engine. The injection of air into the exhaust gases promotes acontinued conversion of the undesirable hydrocarbon and carbon monoxidecomponents of the exhaust gases to relatively harmless carbon dioxide and water.

An air pump mounted on the front of the engine, and belt driven from the waterpump pulley, supplies air under pressure through hoses and a check valve anddistribution manifold to injectors in each exhaust port in the engine cylinderhead. The check valve prevents high pressure exhaust gases from blowing backinto the air pump due to, for examp le, pump drive failure.

Air from the pump is also supplied to a gulp valve, the outlet of which is con­nected to the engine inlet manifold. A small bore sensing pipe connected betweenthe inlet manifold and the diaphragm chamber of the gulp valve relays changesin manifold depression to the valve which will open under -certain conditionssuch as those created by deceleration or engine overrun.

When the gulp valve opens a small quantity of air is admitted directly into theinlet manifold to lean off the rich air/fuel mixture which is present in the manifoldunder conditions immediately following throttle closure. This mixture, havingbeen reduced to a burnable condition, combines with engine inlet charge forcombustion in the engine cylinders in the normal way.

The carburetters are manufactured to a special exhaust emission specificationand are tuned to give the maximum emission control consistent with retainingvehicle performance and driveability. The metering needle is arranged in such amanner that it is always lightly spring loaded against the side of the jet to ensureconsistency of fuel metering. A spring loaded valve incorporated in the throttle

. disc limits the inlet manifold depression and ensures that during conditions ofengine overrun the air/fuel mixture enters the engine cylinders in a burnablecondition consistent with low emission levels.

The ignition distributor is tuned with slightly retarded ignition at low enginer.p .m. compared with non-emission equipped vehicles, and the timing is balancedbetween mechanical and vacuum characteristics to give optimum timing con­sistent with low emissions.

Pu rge line To check, disconnect the purge line from the rocker cover elbow. Examine therestrictor orifice of the restriction formed in the elbow for obstruction. Clear any dirt or

deposits from the restrictor orifice, using a length of wire.

Lubrication Un screw the damper cap at the top of the carbu ret ter and withdraw the damper.Fig . 2 Top up with clean engine oil to bring the oil level 1 inch below the top of the

carburetter damper tub e. Push the damper assembly back into position an dscrew in the cap . Under no circumstances shoul d heavy bodied lubricant beused . Failure to lubricate the piston damper ma y cause the piston to flutter an dreduce acceleration and have an adverse effect on exhaust emission.

Tuning The efficient operation of the engine and exhaus t emission control equipmentFig. 3 depends not only on correct carburetter settings but also on correct ignition

timing , contact breaker and spark plugs and valve rocker clearances. It is essentialthat these items are checked before adjusting the carburetters. Tuning of thecarburetters is confined to setting the idle and-fast idle speeds and the mixturesetting at idle speed. Adjustments should only be undertaken on cars required toconform with exhaust emission control regulations if the use of a reliable tacho­mete r, carburetter balance meter and an exhaust gas analyser (CO mete r) isavailable.

1. Remove the air cleaners.

2. Top up the carburetter piston dampers with recommended engine oil to thecorrect level.

3. Check the throttle control for correct functioni ng.

4. Ensure that the mixture control (choke) will return fully, that the cablehas T6 in. (2 mm .) free play (1) before it starts to pull on the lever and a smallclearance exists between the fast idle screws (2) and their cams.

5. Raise each carburetter lifting pin (3), release the pin and check that thepiston falls freely on to the bridge of the carburetter, indicated by a distinctmetallic click . Consult your D istributor/Dealer if the piston fails to fallfreely .

6. Connect a reliable tachometer.

7. Start the engine and run it at a fast idle speed un til it attains normal runningtemperature then run it for a further five minutes.

8. Increase the engine speed to 2,500 rev./min. for 30 seconds.

N OTE.-Tuning can now be commenced. If delay pre vents the adjustmentbeing completed within three minutes, increase the engine speed to 2,500 rev.jrnin.for 30 seconds and then continue tuning. Repeat thi s clearing procedure at threeminute inte rvals 'until tuning is completed.

9. Check the idle speed (tachometer), see 'GENERAL DATA' and check thecarburetters for balanced air intake using a balance meter.

10. If the balance is not correct, adjust by turning the throttle adjusting screw(4) on one of the carburetters . Then adjust the idle speed by turning thethrottle adjusting screw (4) on each carburetter by the same amount unti l thecorrect idle speed is obt ained. Re-check the carburetter bal ance .Check th e th rottle shaft pin clearance and adjust if necessary-see pa ragraph17.

If a smooth idle at the correct speed and balance is not obtainable adjust theidle speed mixture setting as follows:

11. Stop the engine. Remove each suction chamber and piston , and screw thejets (5) up until the y are flush with the bridge of the carburett er or up asfar as po ssible. Turn down the jet adjusting nut (5) on each carburett er twocomplete turns. Refit the piston and suction chambers and top up the pistondamper oil levels.
