Dirty or fouled plugs - full of soot?

So the past couple years since I have been using my rebuilt A4, I have noticed my spark plugs are way too dirty. I thought maybe I was running too rich? I had my rpm set to about 500 which may be the problem? Could I have a bad carb that causes issues with fuel?

I will be rebuilding my carb this Winter and come Spring commission, I will be sure to set my rpm’s back to 800 minimum and set my fuel mixture to be more precise…any concerns here with how nasty they look though?
