Running rich-what does this look like to you?

[Dhos1]

Running rich, can seriously smell it...does this plug look to be a symptom. I looked at a picture, but it looks normal...thoughts? Gapped at 28, possibly too tight...maybe go to 35?

I dont know if its the picture but it looks kind of brown. How long has the plug been on?

See, thats the thing. Maybe 5 months tops...cars rarely driven. It is orangish/brown

That brown crap could be gas additive, MTBE, or a octane booster you added??
The pic isn't in focus, so it's hard to tell where the timing on the ground strap is, nor the deposits on the thread base.
If you want to "read" plugs, start w/ a fresh set.
I cut the threaded part off, and look at the porcelain..I also have an otoscope, that allows looking into the plug, w/o cutting the threads off..Not as good, but ....
