Just for ****s and grins, how many of you have ever encountered one of
the early Champion spark plugs which comes apart for cleaning?

Mine was pretty beat up when I found it at an antique store in Minnesota.

I run a set of similar plugs in my 1937 Harley. They were also made
by Champion, but badged H-D. You can still buy repop's of these he
http://aaok.com/photos/parts/2399.jpg They come apart by using a
spanner type tool to unscrew th' lock ring.

Costs $88 per pair. Th' original H-D plugs go for *big* money,
sometimes found on ebay.

Many brands of British sparkplugs used in the '50's could be disassembled
for cleaning. Sparkplugs used to be relatively much more expensive; my price
list for 1940 Chrysler parts has them at well over a dollar, as I recall.
