Hello,
I am hoping someone on here can help me. As of Monday I become the proud owner of a mocha Singer 301. But I am haivng problems with her tension. I have done everything I can think of to 'fix' it. I even called the sewing repair man and they START their cleaning and tension adjustments at $69.95! UGH
So I am turning to you all for help.
Here is what I have tried:
.
I have
(1) put in a new needle
(2) re=threaded it several times -left to right
(3) re threaded the bobbin (which is all in great shape!)
(4) bobbin & top thread are the same threads,
(5) cleaned in and around bobbin case and machine
What happens is that once I start sewing the top thread gets REALLY loose and comes un-done from the needle and so I stop. without even making a stitch.
What should I try next?
Tensions is one area on machine I have never been very good at. I usually just take them to a repair man to fix, but last time I had to do that it was only $35.00! I'd prefer to learn how to fix it myself, with yall's help of course.
Thanks everyone! This is my 'new' machine :)

There is a thread on here about vintage machines, I think you should go ask there. Good luck

I don't have a 301 but I think it threads like its little sister the Featherweight, Right to Left. Try this and see if it is the magic fix!

I am unable to help you or myself! I've been struggling with the same problem with my Singer 15-91 & for the life of me can't get it fixed. My list of what I tried looks identical to yours! So...I'm biting the bullet & taking it to the repair shop. Otherwise I may never get to use it & I want to because it is the only machine I have that I can use for FMQ.

My 301 threads right to left as well.
Try that and see, it should make a difference.

Blessings,
Sandi

My other suggestion would be to sew into a leader or a small scrap of fabric or hang on to the threads when you start. yes, right to left threading.

I had the same problem the other day with my 301 drove me crazy, then I threaded it as the others have said right to left and it worked.

That's diff your problem...Right to Left...Also make sure you threaded your bobbin the right way thru the slide piece in your bobbin case...If you do that wrong it also causes that problem...

Also don't forget to give it a good oiling and greasing...Did it come with a booklet showing you where and how...You can find them online or on ebay.

okay Ill go try the right to left and see how it does,
Thanks everyone. I knew yall could help me!
