I have a 2007 Sportsman 450 that the last couple seasons has give me issues with hesitation when crossing water (floorboard deep or even less) or at WOT uphill. It will choke and sputter, chug along and not stall, and one the water is crossed or hill is crested it will come back to life and off I go. It will occasionally give me the same issue when going from a stop to WOT on dry level ground.

I've cleaned/changed the plug, breathers, and filters. I've cleaned the carb about 3 seasons ago as well. It only has about 200hrs on it and just over 1000km. I've looked at almost everything, but if someone can shed some light on this, it would be appreciated.

Thanks.
