The perfect sparkplug?

[Inthewoods]

I just did a throtle chop today in 4th gear WOT for about 10sec and the color on my plug is the perfect color (Mocha Brown).
My concern is that there is hight corbon deposits on the porslin and some on the electrode and also some on the bent thingy sorry about the incorrect term, is this just my oil or is it somthing else, I run Belray racing oil and the card is at stock settings internaly.

Do a forum search for PLUG READING in this forum. There is a helpful thread with some pics...

Must do a plug chop with a brand new plug. Read the color down low on the insulator where it comes out of the body of the plug. A flashlight and a good set of eyes are helpfull.
