reading plugs at idle ? can it be done.

hey guys i always hear about reading your plugs after a wide open pass or a 2nd gear pull, well what about at idle, i have installed a wide band gauge and have got my idle afr to about 13.4:1 but has had it as lean as 14.1:1 and i am still getting my plugs sooty on the porcelain !

What carb? What application? What fuel? How are you tuning it? What timing? What ignition? What plugs? What compression? What heads? Etc???
