I have an bayou 220 fourwheeler 2 wheel drive and it all of a sudden stared burning spark plugs fast in about thrre days it needs a new spark plug and the old one is BLACK but when i replace it it fires right up again i need some help i think it might be fuel mixture but i dont know any help is appreciated!!!

 

scott, if your plug is black, your mixture is too rich. Before you go twiddling with screws, check the airflow path. Make sure filter is clean, no blockages, etc.

 

I have done this it is clear how do i make it not so rich would i adjust the jet screw inside the carburetor???
