Welcome. As Leon mentioned there are a lot of different Nelco machines out there probably beginning in the 1950s. Most domestic Japanese and Taiwanese machine would use standard
System 15x1 ,130/705H needles.. A lot of the machines would thread from left to right (with the flat side of the needle on the right) or from front to back (with the flat of the needle to the back).
A lot of them that I have seen take a class 15 bobbin with the 1 o'clock finger. I think that most would thread as shown at

When you thread the machine, you should have the presser foot up, so that the thread will go between the tension discs. After going between the tension discs, you need to hold the top thread and bring the tension spring with the thread past the hook or notch on the tension assembly.
Another thing that I've been known to forget is to make sure that there is some pressure on the presser foot. Yes, you can do FMQ or darning without any pressure, but it doesn't sew seams very well. Also, many of these machines of this era have a knob to drop the feed for silk sewing or embroidery. For sewing seems you will want the feed dogs in the normal position.
Indeed a picture of your machine would help us, help you. We like pictures. In order to post pictures on Quilting Board, you will probably need to reduce or compress the picture to a
file size that is smaller than 2MB. How to post images can be found at

I have found that only the big red "Reply" button or "Quote" work to give me the paper clip icon to work for adding pictures.
