Chances are it's not actually the throat plate's fault.

I've worked on machines that had multiple parts very worn and multiple adjustments made to compensate for that wear. When I install a new part that is to spec, things are suddenly too tight and all manner of problems manifest, setting off a cascade of adjustments and new parts.

Totally. And the fact that I have an extra throat plate to experiment with is a plus too. I’ve watched you Adler 67 video at least 50 times haha. That’s what started me down this path. 

I remember installing a brand new hook and, as you said, everything was slightly off. Had to move the hook assembly over slightly to make room (which means someone had compensated for the wear before) with the two fasteners that were stuck in your video. 

Going to pull out the mechanics manual and double check the proper distance between hook tip and needle.
