It just rattles badly at idle, i'd adjust it and it'd be fine for a few days and begin to rattle again. My guess is the preload spring gets hot and looses uh, springyness

Added a random spring from a carburetor spring kit and it's enough I don't hear it so I'm cool.

That is a neat fix you came up with tho.
