^^ good rule for most things Sparky, but maybe not all. I'd take what i can get

Never found one that could not be solved by a good bouncing of the tip on grass (more serious than the wobbling described above) and maybe some washing out the joint at same time if it has stuck halfway like this one, and the obvious twist n pull. and when twisting if it moves keep going in same direction and puling like you are trying to undo a bolt. Often reversing makes the grit bunch up again.
However there was a gorilla described here a couple years back that was too tight and after the 100 ideas from seabreeze members it was actually a factory fault, tolerance problem I guess, that they covered. Search up the threads, there are plenty of them here
