Ok I cleaned out the bobbin and feed dogs and that has seemed to help alot. Im also using Superior so fine thread and that's helping too. I'm sewing along all happy tonight and then all of a sudden the machine gets stuck in reverse again. I was tacking the end before I started and then it wouldn't go forward until I turned off the machine and turned it back on. What the heck is going on? Could I have gotten 2 lemons or is this something I'm doing?
