Do you mean the porcealin that's inside the combustion chamber or the porcealin outside? If it's brown on the Inside it means that it's running correctly, but if it's brown after idling for awhile then you should do a "plug chop" (run it at or near top speed and shut the engine down at top speed and remove plug) A plug chop is the real only accurate way to make sure your mixture is right. Black means it's rich and white means it's too lean A golden brown is preffered, but slightly rich doesn't hurt. If it's lean, the engine could seize.
