When I first got my 301 my tension was crazy, so I took apart the tension unit and put it back together. It wasn't dirty or anything so I don't know what the deal was. Apparently giving it the stink eye and then putting it all back together was what it needed. Also, the bobbin case was acting so crazy- finally I put my 221 bobbin case in there instead, since they are the same, and I realized it was definitely not my machine, it was the danged bobbin case. I ended up taking that tiny little screw out that you turn to adjust the bobbin tension. Put it back in and adjusted a bit and voila, perfect tension.
