I recently have been having problems with 2 of my yoyos, my Duncan Speed Beetle and my F.A.S.T 201.
The problem is that they can’t sleep anymore. They travel down the string and immediately come back up.
The reason for concern is that I am ordering a new yoyo and do not want the new yoyo to become like the previous ones.
Plus, the Duncan Speed Beetle couldn’t sleep after about 30 minutes of playing with it. In that 30 minutes of playing with it, I made it sleep perfectly fine.
The Fast 201 was working fine yesterday. Today, after playing with it for an hour, it just couldn’t sleep.
It seems like the bearing doesn’t spin anymore on both of the yoyos.
