Today I cleaned and set the points on my 1922 model A. Got a good spark. Then used a wire with clips to the spark plug and it sparked. I see no numbers on this old Champion. Are they available?
Yes, many old stock plugs on ebay turn up from time to time.
The Champion W10-stock# 510 is readily available as well. Only thing with this one is the insulator is long……may not look correct if you know what I mean.
el cheapo modern equivalent – Autolite 3076, readily available for about 4 bucks a plug.
Hope it helps eh.

He's livin' in his own private Idaho..... I hope to go out quietly in my sleep, like my grand-dad did..... and not screaming, like the passengers in his car...
