Reading spark plugs
1984 12A FB
Leading plugs are black with carbon. Trailing are clean and practically look new.
I've checked the ingnition system. All leads are firing correctly.
Thoughts?

black with carbon could be running rich, burning too much oil, or just old, or all the above. Being as your trailing plugs look good, I would find it hard to believe that your burning oil.
Plugs that look light greyish/brownish means your engine is running almost perfect.

I think it's hard to draw conclusions without pictures, but seems like the trailing plugs by their position and being shielded by the housing would be prone to more carbon. Be sure to look for erosion at the electrode too.

No, it wasn't.
From the beginning this thread was a waste of our time. Like telling the doctor that you're not feeling well and asking him to give you his "thoughts" over the phone. When told twice that pictures were needed you told us you were "out of pocket"?
