the instant of spark plug firing is determined by the opening of the distributor ignition breaker points and will change any time the point gap or Dwell angle is changed.In addition,normal wear on the breaker point rubbing block will change the dwell and effect the timing.
While cars equipped with the new"breakerless Electronic Ignition Systems" will not normally change timing since there are no breaker points,the timing light can still be used to note changes in timing caused by troubles in the ignition system as well as for resetting timing when components are changed.
