I just changed the 10mf and 2.2mf caps. I didn't have any 22mf caps on hand, I'll have to source some.

It changed, but did not fix the problem. Now the hunting is slower, but it still doesn't hold speed and cancels. I'll report back when I have the last 2 caps changed.

EDIT: changed the last two, there was a slight improvement but not much
