And I have no idea how to fix it. Just finding out all the little things that werent told to me when it was sold. This one needs to be fixed though. Any ideas?

 

like the slider or the leaner lol

 

The slider. I adjusted the tension and it still wouldn't hold. So I went looking elsewhere and found a stack of quarters lying in the claw that catches the seat. Didn't think anything could get in there. It's fixed.
