SERVICE RELEASE N30

NATURE OF RELEASE: Timing markings on rotor MODELS AFFECTED: Late 1971 Commando (all models) DISTRIBUTION: Worldwide (for general distribution) EXPLANATION: The Lucas generator rotor now being received for production has two timing markings opposite each other. Dealers and owners should note that the presence of the surplus marking will not affect timing, either static or with a stroboscope. To explain - the engine must be running for a stroboscope to be used. Setting the timing by the wrong marking would mean the spark was timed at bottom dead centre end the engine would not run. If the engine is timed on the correct stroke, the stroboscope will not pick up the wrong marking. Similarly with static timing, only the correct marking will align with the calibrated scale in the primary case with the piston near top dead centre on the Firing stroke for the cylinder being timed.   ACTION: Time ignition as previously instructed.
