Thanks. Would I be ordering the Singer beehive tension spring? It looks like mine....(edited to add that I just noticed it's out of stock. Too bad. I've ordered from Jenny before.)

Or did you mean I should order a whole new assembly? The only Kenmore one I saw was for the 158s. Are they interchangeable? (see - total noob!!)
