This one might help more (it's the other one you mentioned), unless people want to take the tensioner off the machine:

That said both have some slightly different information in them so it's worth watching both if you have time. Both videos were "Stream of consciousness" no script at all.
The other note (which is in the description but a lot of people don't read them): The "2 setting" I mention toward the end of the video works for most full sized tensioners. For the smaller tensioners, like the 301 and the Featherweight, I find that the setting is full tight when the post is flush - between 9 and 10.
PS, I agree, it's the tension release pin. The bobbin tension wouldn't have anything to do with the top tension not releasing.
