Re: [HSS] Spark Plugs

I should read all the postings before jumping in with a reply! I have just

checked in my box of goodies, and found an original set of AC G14 plugs

which are original equipment for Essex 6 and F-head Hudson motors. They are

3/4" reach. I bought these on ebay, and will probably never use them in my

lifetime, but they sure looke nice! Also a set of KLGTML 50 which are also

3/4" reach, so I assume a replacement. These of course are all made of

unobtainium. For all intents and purposes, the universal Champion D16's are

quite suitable. I believe D21 and D23's are still available from Champion.

The D23's are an extremely hot plug, and have an extended electrode similar

to the originals. The KLG's are an extrtemely well-made plug, being in two

pieces, the top section demountable for cleaning.
