    A few sellers are offering sets of obsolete spark plugs for bid on ebay. H-11, autolite 217s etc. Question, hornets used H-11s direct crossover is the Autolite 217 a bit hotter than the Champion H-10 AC 45L & C45L, Autolite 216. Does anyone have an opinion, which is the best for the fuel today? I did not notice any performance differance, ie, pre detonation vs carbon fouling.

    With today's gas, best to use one or two steps colder. H-10 or H-8 Walt.
