I have a Singer model 27 (H172728). I was cleaning it, thanks for the tutes Billy, and I think I'm missing something on the tensioner. I don't know much at all about sewing machines but the manual I downloaded showed a hook like thingy on the tensioner that the thread is supposed to go through but I dont have one of those. It looks like the "hook thingy" is part of the spring (not the thick one you can easily see but the other one), but mine doesn't have the "hook thingy". I posted a picture, I hope I'm making sense... lol.

You are missing the check spring, Dana I have some 27 parts, I will look and see if I have one.
