You don't mention if you looked at the check spring, suggested earlier.  Here's a recent treatise on all things Check Spring from Wizcrafts. Proper check spring function is critical: 

 

Tension seems about the same as a PEZ dispenser which should be fine.  I have never adjusted it.  The location of the spring seems like its at about a 9 position in reference to a clock.  A lot online seem to be more at at 9:30 position or higher.  Should I reposition it?

I have seen many varying videos online and there's no consensus.  Does the thread go over the pin or not?

I typically do not have it over the pin, but it is in this photo.

On the 111W's and everywhere I've seen that tension setup, it makes an "S" shape. It does not go over the pin.

It's hard to say from a distance. Some of it is going to depend on the thickness of your material. Wiz gives 3 adjustments to look at in the post I linked earlier and they all work together. It's well worth understanding how the check spring works.
