Why in the world would you quit your job over a moped.
No bolts there, just studs and nuts...
What is spinning, the whole thing(Nut n stud). Or just the nut on the stud...if it's just the nut ur gonna have to pull or lever the nut while spinning so it catches a thread n comes out...then replace the stud
If they're both spinning then the case is stripped and it'll most likely pull right out while removing the jug. Then ur gonna have to re tap and put in a new stud.
