[Healeys] Spark plugs renewal

[Kees Oudesluijs]

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.
