That's what I was thinking. As I recall my Mom's 301 has an arrow on the needle plate showing the direction of the thread. And it's definitely right to left (inside to outside).

I downloaded one for my Mom's machine cause it hadn't been oiled in ages and I wasn't sure of all the places to lube and oil. There's also lots of other useful information in the booklet and they're pretty easy to get.

My 301 threads from right to left as well.
I couldn't really tell because the picture is too small, but i believe you are missing a guide. To the left of the spool and just behind the front guide. It would attach to the back of the machine. I think you will find a small hole on the back left of the machine at the top. I bought a set of guides on Ebay for a total of $9. Check out some pictures on the Singer site to see it. DO you have the book? you can d/l that free from Singer.

THAT WAS IT!!! i THREADED the machine from RIGHT TO LEFT and it sew like a dream !!! Maybe I'll call her 'Dreamy'???? LOL

Oh I am so excited now to go sew something! THANKS EVERYONE AGAIN FOR THE HELP!

Awesome, I have been following this thread closely to see if you got your machine to sew properly.

I know I love mine and she sews like a dream too, but I haven't named her yet.
I have a black shortbed 301.

Blessings to you,
Sandi

I was going to make the same suggestions about the threading. Glad it's all working now. Have fun!
