Hi all, I have an Yppy that runs properly in one direction and doesn't seem to be strong enough to play into the other direction. It doesn't matter if I use the directional switch, let is auto-reverse or stop and switch direction. It'll turn for a second and then just stop. What could be the likely cause of this? I haven't opened up an Yppy yet, I read it can be a Pita due to the framework. I'd love to have an idea what I get into before I start and appreciate any suggestions. Thanks!
