Air pollution
The carburetter incorporates features which assist in reducing exhaust emissions.
control
Maladjustment or the fitting of parts not to the required specification may render
these features ineffective.
Lubrication
Each damper reservoir must be topped up periodically with a recommended

engine oil. Under no circumstances should
heavy-bodied
lubricant be used.
Unscrew the damper cap, withdraw the damper, and top up the reservoir until
the oil level (arrowed) is
+
in. (12 mm.) above the top of the hollow piston rod.
Push the damper assembly back into position and screw the cap firmly into the
reservoir.
Accelerator
Lubricate the carburetter accelerator and choke linkages and cables, and the
accelerator pedal fulcrum.
Carburetter
The efficient operation of the engine and any exhaust emission control equipment
tuning
which may be fitted depends on correct carburetter settings, ignition timing,

valve rocker clearance, distributor contact breaker and plug gaps. It is essential
that these items are checked before adjusting the carburetters.
Tuning of the carburetters is confined to setting the idle and fast idle speeds and
the mixture setting at idle speed. Adjustments should only be undertaken on cars
required to conform with exhaust emission control regulations if the use of a
reliable tachometer, carburetter balance meter and an exhaust gas analyser
(CO meter) is. available.
1. Remove the air cleaners.
2.
Top up the carburetter piston dampers with recommended engine oil to the
correct level if necessary.
3.
Check the throttle control for correct functioning.
