Hey kids, I just disassembled and cleaned the carb on my brothers 2001 Suzuki 300 Kiing Quad. It is a thumper. His original complaint was that the thing ran fine when cold, but flooded and died when it warmed up. When I reinstalled the carb (sans airbox) it fired right up but idled real high and the exhaust pipe got very hot and glowed red in short order. It seems to be getting plenty of fuel. It also backfired when shut off. So my question is, WTF? Any ideas?
