You should be able to remove the protective cover that houses the 33\45 switch, the on\off switch, and the speed adjustment. With that cover off determine if the belt has been installed inside out. The grippy side could be on the outside and the non-grippy side is thoroughly warn. I did this once, although my speed issues were not nearly as severe.
With cover off you should be able to observe the driver pulley. If this is slow then you have a problem. I would make these observations and contact a good SOTA dealer or SOTA themselves. I have always found Donna at SOTA an easy person to speak to. If you e-mail SOTA, I have found them very responsive.
Good luck.
