Sorry about that,was thinking about the Scrambler 400.. I'd check the valve clearance first..006 intake and exhaust. On that new carb is it a Mikuni or one of those knock of Chinese carbs? Valve clearances are checked when the cam sprocket index pin is straight up,lobes down.Same as the Sportsman 500.One other thing that new owners aren't aware of is that thumb lever slack must not be more than 1/8" or etc contacts can touch and cause no spark or erratic problems. Cable adjuster is down from the throttle housing.
