A Lucas 35DLM8 distributor is employed. This has a
conventional vacuum advance unit and centrifugal
automatic advance mechanism.
A pick-up module, in conjunction with a rotating timing

signals. These are applied to an electronic ignition
amplifier module mounted on side of distributor body.
NOTE: Pick-up air gap is factory set. Do
not adjust gap unless pick-up is being
changed or base plate has been moved.
Use a non-ferrous feeler gauge to set air gap.
