I somehow broke off one side of the oiler adjuster screw head when I was turning to get more oil if I could (didn't remember if I had it all the way or not). It ended up being all the way I guess...hence the broken screw. It isn't bothering me right now as it's just stuck on max but I may eventually want to lower it. Is there an easy replacement screw and how difficult would it be to be able to take the screw out without the other side of the head?
