I took my number one spark plug out today to find TDC and noticed some black stuff on it:



I blew a little bit of it off, but is this normal or could it mean I'm running too rich?

Thanks in advance

They look good for as old as they are. The black stuff you see is carbon. If it was rich the porcelin would be black, not the brown color you've got.

I appreciate the help. Sorry, I'm a little new to the electrical system of the car.
Scott, would you be able to try and send that email to [email protected] instead? For some reason the mailbox you sent it to, took all the pictures out and formatted it weird.

Thanks
