I have only had them turn color like that when the engine is run too lean and gets to hot. You been tweaking that HS needle?

How much smoke do you have coming out of the pipe when you hit the gas? A lot or a little or what? cause you need smoke!!!

I've taken out black plugs due to starting/running rich, where I was coming from.

leave well alone do not polish it or use anything like sand paper wire wool etc its probably the oil in the fuel, does your fuel have castor oil in it?.if so thats the culprit!!.when you say black do you mean BLACK or brown?if brown its def the oil and it natural .
