Suzuki - Needle Valve Assembly - 13370-09F00

I received the quad and several things had been checked and "adjusted"... Well first the quad would start and run cold and you could rev it up for approx 1 minute. After the engine had run if you attempted to rev it up the engine would shut off, I monitored spark and sure enough the spark was lost when the engine shut off. I read several posts describing this issue and found that the regulator-rectifier had a bad diode. I ordered the new R-R and after replacing it the engine ran for approx 5 minutes and was able to be revved up then the engine started to quit again, but this time it wasn't losing spark. I had looked when I received the quad and there was some fuel in the tank, well this time the tank was empty... I suspected that the oil was now contaminated with fuel because the needle and seat was bad and sure enough it was. Replacing the needle and seat was easy enough and low and behold the engine runs as good as new.
