hey everybody whats up, I just bought a 94 Polaris Sportsman 400 2 stroke. after finding where everything went I've got it put together. My problem is when I tried to start it ,it would turn over fine ,its getting fuel ,but it will only park on the first rev. I pulled the plug grounded it and watched the thing sparks one time then quits. Is there a limiter or safety switch I'm missing somewhere. confused.
