Loop 1080 vibe(on the string)

Hey guys I need some help diagnosing a problem with one of my loop 1080s. When I throw it down and it’s sleeping there’s a lot of vibe on the string, not necessarily the yoyo it self. So I think the gap might be too tight right now or I have to add some lube to it. Either way, it’s not performing as well as my other one.
I just want some feed back before I do anything thanks

Probably the starburst rubbing the string, try loosening the gap

The starburst should not rub enough that it affects spin time. It should make mild noise as opposed to loud screeching sound. Widen the gap and add lube.
