Not sure whats wrong with this unit, looking for a little help. The unit idles great but when you give it throttle it chugs and doesnt make power? I have cleaned the carb, changed the plug, new air cleaner, checked spark, fuel, cleaned the stator. If you hold the throttle wide open every once and a while it will take off. This quad has seen a lot of water and mud, not sure if this matters but it is a 2 stroke. A
