very well done article. If the service man says the tension is set correctly then usually it is the user that has a problem some where else. I'm sure this venture has taught a ton of things. I learn more from the snafu than when things go right. Whether the machine is a needle feed machine or a serger, the tension will work just like any other tension. When adjusted right the thread should just drag a very little - pressure foot down of course. The bobbin should just drag a very little, too. Too much on either will give you uneven stitches. Loops on the bottom - something wrong on top. Make sure the pressure foot is down when you sew. It is very easy to forget to put it down when you do free motion. I made a link a while back about tension problems maybe something will stand out.
