Do these spark plugs look okay?
I replaced them about 10k miles ago when I did my upper head swap (broken timing belt). Decided I'd finally check on them. Do these look normal? Reason I ask is because my old plugs were all solid dark brown in coloring...these ones are fairly white with what looks like little hot spots on them.
Cylinder 1 smelt quite a bit like gas too. Do you think I'm running rich? They are PFR5N-11 plugs gapped to .044". Thanks!

It may have smelled like gas from cranking just before pulling the plug. You're not showing a plug from a rich cylinder at all. Would you mind taking a shot without flash to get the color to show more accurately?

Thanks for the pic. The flash actually was off, that was just my shop lights. They were a very light brown color with lots of white powder deposits. I was wondering what the white powder was on the plugs? Is that normal to have on them? Thanks.

That table/image is the best I've seen yet. Trust it. If your plugs look like anything from the "green" section, don't sweat it. White is burned-off stuff from running hot, as spark plugs do.
