I thought you might mean an old elna too, but I guess it could be a new Singer maybe. But the way the thread tension works on a serger is just much like on also a sewing machine. Except you got more threads and loopers not a bobbin. But on both of them, it's not just the thread tension on any one thread that counts as to pulling that particular thread more or less in one direction. Instead, it's actually both or more of all of them, all together.
If an old elna, I would not worry about a exact # on a dail in a old book, or some way newer than the machine, new Utube movie or such all that much, at this point, just since machine older now, and any # might work better than before, and really just at any time by your actual fabric and thread each time too. So line up 5 of them (all old and in a row) and give them all the same fabric and thread, and even all the tension #'s on all of them now, might not all sew best at the exact same #'s for everything.
I think standard practice is you should thread up with threads matching your thread path color coded colors every time you get a new machine to you, no matter how old or or new it really is. Then when you practice sew on it a bit, it makes it much more easy to even see what thread is ending up where each time and isolate that out. You would think if it looks like you got a bit too much thread feeding out someplace, that you always want to tighten that threads tension dial to get less thread there, but not always. Just because what factors into how much thread is feeding out each time, is also the other thread(s) hooked into that one and pulling on it too.and also just your cutting width there too.
So thread up with all those different colors, matching to the thread paths, and then since you are not getting what you want, by changing that looper tension just tighter and tighter, find the thread color that hooks into it, and try turning that tension knob or dial actually looser instead. It does have to do with your cutting width though also. Sometimes more quick and easy to just make the cutting width a bit more wide or narrow instead of having to change tensions back and forth with all sorts of factors each time.
If it's a new Singer maybe the place you bought it from might be willing to sit and sew with you a while. As maybe they owe you something, like showing you how to do that. If it's an old elna instead, and you did not buy it used from the exact same place,you just walked into each time, I doubt anyone there, if you can find a place, would be willing to do that free for you instead at all though. As probably just no incentive in it, for them at all either. Maybe if you offered to pay for a sewing lesson on it, instead though?
