i was out running my buddies warrior that i got running for him and to me it seems real dead in mid range. you really had to work the throttle in the corners to make it slide around. on low end and top end it had power but mid you had to keep your rpms rather high in the corner. i couldnt see any adjustment screws on the car for a/f or high speed. i didnt take a close look but i take the carb had an adjustable needle and slide?
