I just got an 888 from jayyo (really smooth, I love it 🙂 ) but on of the stacks is spinning really slowly. like if I stop the yoyo, one side will keep going, and the other stops in like a second. I tried putting on one of the bearing from my g5 to see if it was just that, but it didn’t really help. what could the problem be? ---

Anything on the hubstacks? Like there might be some dirt on the hubstacks part just like the bearing seat the yoyo. Clean the bearing that is stuck. Might help. ---
