Or maybe you have to shake the bolt off a little. If it drops right off (into your hand as you turn it vertical), it's too loose. If you definitely have to pull the bolt off, it's too tight. If it is in between, it's good and don't mess with it unless it leaks.
That will tell you if you need a lvl 10 kit or not.
