Carburettor (Weber 2V type) - fast idle speed adjustment
1 This procedure does not apply to models fitted with a carburettor stepper motor, for which no adjustment is possible.
2 Check the idle speed and mixture. The idle speed must be correct before attempting to check or adjust the fast idle speed.
3 With the engine at normal operating temperature, and a tachometer connected in accordance with the manufacturer’s instructions, proceed as follows.
4 Remove the air cleaner.
5 Partially 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)

carburettor (2.0 litre models)
and on 2.0 litre models the fast idle adjustment screw rests on the highest step of the fast idle cam (see illustration).
6 Release 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.
7 Without 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.
8 On completion of adjustment, stop the engine and disconnect the tachometer, then refit the air cleaner.
