roller in accelerator cam 1998 150 2 stroke

Does anyone has the part number and where to buy the small roller that goes agains the acceleration cam in a 1998 150 two strokes. The rollers are made of hard plastic with apparently a bearing inside. the plastic is worn in mine and there is too much friction with the acceleration cams.

thanks
