Looking at your vid, it looks like it is running fine. Roll with it. I would pull the plug on it and see how it looks. If it is really dark, like almost black, you are running rich.
There is a point in which the buggy will start running like crap from being too rich. Your's is not there per your vids. If you do find that your running too rich via reading the plug, what you have to gain is a little power. Running richer has the advantage of giving you a little extra engine protection at the cost of losing a little power. If you get just the right air fuel mixture, you will be running at ultimate power. Can't really say where you are at until you see what the plug looks like.
I don't think you are running so rich that you'll wash the rings out. It looks to be running pretty good.
