MFI crossbar return spring

[chauser]

Hi

My crossbar return spring appears to have slipped (arrow), I think it should be on top (star).

Someone previously also repositioned the pivot point of the spring - not sure why (pict2)

I'd like to either replace, or reposition the current spring, as my idle is not returning to set point always.

In either case I'm not sure how to approach that - lots of spring tension!

Suggestions for repositioning or replacing with new?

edit: is the other end inserted into the the hole

No, the pivot end can be seen in 2nd picture by the large washer

In general, how do you wind spring up say 1 more turn?
