I would check the hydro lever adjustment under the tower area. You pull the battery and then use either a crow foot or a wrench(1 and 1/16 or 1 and 1/8) tighten down until drag is just enough to hold lever . I had to make a wrench work by cutting it in half and grinding on it to fit. My cub was like a speed demon until i did this adjustment. What a difference it makes.
