Spark plug color?

[Evildomain]

Took my spark plug out after running yesterday. Snapped a picture


so you guys could take a look. Is it a good color? When I first got


the truck it had a loose head and the idle, low and high speed screws


were all screwed up. The plug was coming out a dark wet oily black


color.

The ceramic portion of the plug in the picture should be a tan color. White is bad, that mean too lean. It looks a bit rich but thats ok. Should take a few high speed runs then stop, pull the plug and check the color of it. This is how I always did it anyhow.

I tried to use the picture that best represents the color but it is a little lighter


than it looks.

The way its sounded and the way the plug looks and you say its a bit lighter you should be right on track.

The truck seems to idle real good. Don't know if that has anything to do with


the boost bottles since I've never run without them. I don't have anything to


compare it to. It's too much hassle to remove them just to see the difference.


If ain't broke, don't fix it....lol
