YYf Loop 900 Gap is Uneven


#1

I bought i pair of white Loop 900s from someone on the forums and I was told they were never played before, and when i got them they looked like they weren’t played. One problem i noticed is that the gap on both yoyos were uneven, i would open the gap a bit and a nickel would slide through about 1/2 of the yoyo then it got snug and wouldn’t go in on the other side. I have heard there were other people with this problem and was wondering if there is anything i could do

Also, i replaced the string on one of them then it suddenly got louder and played differently than before, does anyone have an idea what might have caused this and how i could fix it
