    <p>No need to change the plugs every 12.000mls. Just check them
      every year or when the idling starts getting a bit rough (can also
      be caused by several other problems like carbs, points, capacitor,
      distributor cap, plug leads). When dirty clean them properly and
      re-gap. Only when worn replace them, which in practice will be
      hardly ever as the yearly mileage is usually rather low.</p>
