Another vote here for slidertogrid's comment in post 19 re: buildup on pulley step. Had this numerous times. It seems to be worst on those with plastic platters too!

The decks with plastic platters are also probably most prone to running fast, after all the motors and idlers were likely designed with the heavier metal ones in mind, the plastic came later. People seem to notice slow running more than fast, after all.

Another thing you can do is adjust the positioning of the rubber idler on the step. I think the steps on these BSRs are actually slightly tapered. There is a brass screw that raises/lowers it. You don't get much range but it might suffice in these cases.
