Alloy inlet manifold

Note: Before adjusting cable ensure that cable is correctly routed and located. Do not attempt to adjust throttle cable or engine idle speed by means of the throttle stop screw.

Alloy inlet manifold

1. Use Microcheck to ensure that throttle potentiometer and stepper motor are synchronised.
2. Switch ignition on, wait 10 seconds and switch ignition off to ensure stepper motor is in setting position.

3. Release cable adjusting nut from abutment bracket.
4. Position outer cable in abutment bracket and adjust cable adjusting nut until it just contacts top of abutment bracket.

5. Alloy inlet manifold: Hold cam in 'throttle closed' position, ensure throttle position screw is in contact with the stepper motor pin. Rotate cable adjusting nut until all slack is taken out of inner cable. Ensure any linkage gap is taken up without opening throttle, see inset.

6. Plastic inlet manifold: Hold throttle cam in contact with throttle stop screw. Rotate cable adjusting nut until all slack is taken out of inner cable. Ensure throttle does not open.

CAUTION: Ensure all free play is removed from outer cable.

7. Locate groove in cable adjusting nut in abutment bracket.
8. Operate throttle pedal and ensure that throttle will open to its stop.
