Consew 227R feed dog eccentric

[Googledave]

Hi all, I was sewing away when my machine begin to sluggishly pierce the leather and stitching changed size(got smaller) Anyway, I went thru the normal stuff and found the set screws on the feed dog eccentric came loose and eccentric(or shaft) spun taking the feed dog out of time with feed shaft.... so how do I place the eccentric in time with the shaft? There are two screws: one an Allen and one a slotted screw. I spun it by hand to figure out time and it looks like the Allen screw fits into the slot in the shaft. But now the machine is harder to spin by hand then before. It doesn’t feel right. So I took the feed dog and fork off and of course the machine spins freely. So I’ve narrowed it down to that eccentric not in time... where is the eccentric lobe supposed to be at its highest point in relation to the feed shaft?  Thanks!!
