I have a question regarding the needle clip setting. I bought a 03 warrior for "cheap" and thought everything was fine, but I started to notice that once the motor was warm it would backfire through the carb at idle and stumble when you grab a handful of throttle. I grabbed my service manual and set to work. every thing pointed to a lean condition. First thing I noticed was the exhaust was just plain wrong. He had cut and pinched the manifold and cut a huge hole in the side of the air box. Ok... crap, got all the exhaust and the air box out of the way, now I see a vacuum hose on the test port going nowhere and the carb mount cracked and de-lamented. So one week later a DG exhaust and a bunch of factory parts show up. Got it all together and torqued to factory specs. It now idles like silk, but still hesitates although its better. DG recommends a 150 main (done) and lowering the clip one position. My question is, where is this clip in the carb and how do I get at it and adjust it? I see it in the exploded view but just cant figure it out. I read post after post and no one elaborates how to adjust it. Sorry for the long back story but now I'm lost. any help will be appreciated.
