Yes, disturbing the rocker assembly requires valve adjusting, but that needs to be part of the maintenance routine anytime any sort of tuneup is done, when the phase of the moon changes, and a bunch of other times. Valve adjustment should be so ingrained into a stovebolt mechanic's routine he can do it in his sleep, hung over, or any other time I can imagine. These old rigs need a LOT of TLC. Setting points, adjusting timing, adjusting valves, filing and re-gapping spark plugs- - - -that's how us old geezers paid the rent and the grocery bill back when the labor rate was $7.50 an hour!
