I picked up a new-old-stock (2009) motorized Lionel aquarium car at York. The belt continues to slip when it reaches a certain spot, leading me to believe me it is stretched or that it has a "memory bump" in it from sitting for nine years. I've tried gently pushing each roller toward its end of the car, but that only helped a bit. I'm thinking of putting some black electrical tape on each of the rollers to increase their "thickness," & thus traction. Has anyone tried this.. or have an alternate idea? Thanks!
