Several years ago the AC-C86 plug was discontinued and it was replaced by the AC-C87 plug, which is also correct for the 1929-32 engines. It just has a different heat range. :) :grin: The Mangy Old Mutt "If It's Not Junk.....It's Not Treasure!"

So if that is ture and everyone knows the original 32 plug was G-10, then the C86 is a little colder. So I would think that a C87 would be better, hotter spark. 32 Confederate Bruce S.
