I think it says 9A-22. Maybe next time you could take the picture of the plug right side up? That would make it easier to read.
again, how many miles? And, what type of fuel are you using?
Plugs shouldn't be read at the tip of the porcelain but down in the body where the porcelain
is cemented to the iron. You should be looking down inside the plug and not at a side view. A strong light and a magnifying glass are required.

Only gas ever in the engine is Shell 93 octane.
Thinking I might be lean at cruise and deeper in the throttle even though the idle smells rich.
Thanks for the help yall.
Sorry for the lack of response, I just haven't had time to mess with the car or the internet this week.
ok-I'll post a stupid question--How do u cut the threads off a plug??? Thanks Steve
