Just pull the vacuum(impulse) line and fuel supply lines at the carb and use a mityvac on the impulse and see how much gas flows. If it's weak stream,could be a weak pump or even the fuel valve could be stopped up.You can eliminate the fuel valve as the problem by pulling the line going from the valve outlet to the pump inlet and turning the valve on. Should flow out in the on and reserve position. If you narrow it down to a fuel pump,they're getting ridiculously cheap on ebay.. Less than 10 bucks.http://www.ebay.com/itm/Fuel-Pump-Fit-Polaris-Sportsman-325-400-500-600-700-1996-2010-2520227-3085275-/121693604623?hash=item1c55810b0f&vxp=mtr
