Did you buy it new or used? I ask because LOTS of times when I buy a vintage machine, it's got stuff in the accessory kit and drawers that go with a different machine or don't have anything to do with any kind of sewing. But then again, you said that it was working, so that couldn't be it.

If it was working fine a week ago, then it's not the foot that needs adjusting, it's the position of the needlebar or the position of the attachment as it's seated on the needlebar.

Are you sure that it's not broken?

Are you sure that you are getting it seated in its proper orientation and that you're using the right thumbscrew to attach it? (if it uses something other than the normal thumbscrew or lever) ( :oops: I forgot you said that you'd taken it off and put it back on several times)

Do all the other feet work properly?

Have you had any hard needle strikes? If so, that could have jarred the needle bar out of position or even bent it out of alignment.

Has the machine been dropped, or has anything perhaps fallen against it hard enough to knock the presser bar or needle bar out of alignment?

I'm sort of grasping at straws, but I hope you can find out what's wrong with it. If you have had a hard needle strike, I would recommend that you take it to a service center and have them take a look at it to make sure that the needlebar hasn't been knocked out of shape.

Good Luck!
