I've got a 97 Challenger with a 110 Rotax. Used it for 3 seasons now and have always had this same problem. Boat will not start (cold or hot) unless the throttle is wide open. It cranks over fine, but the engine won't fire. If I have the throttle full, it starts right away, then I just quickly move the throttle back to idle, and it runs great. <br />I've changed check valves both at the tank and near the engine. not sure what to try next. <br />Anyone have this problem or know of the solution?
