1 The throttle cable is connected to a spring-loaded reel which pivots on the face of the cylinder head. On certain models, the reel then operates the throttle lever on the carburettor through a plastic balljointed control rod.

2 Sparingly apply a few drops of light oil to the throttle spindles, linkage pivot points and to the cable itself. Similarly lubricate the exposed ends of the choke cable (where fitted).

3 Check that there is a small amount of slackness in the cable so that the throttle linkage closes fully with the accelerator pedal released. Also check that full throttle can be obtained with the accelerator pedal fully depressed.

4 If there is any doubt about the cable adjustment, refer to the relevant Parts of Chapter 4 for the full adjustment procedure.
