Please forgive if it’s not in the right place. this is my first time posting. I am having a problem with my sewing maching. It’s an industrial machine and I am threading it correctly with new string. However lately, the stitches are longer than they should be and spaced out more than they should. At some points while sewing the thread also snaps. Upper thread. I tried adjusting the stitch width and such from the button gage (from 1 to 6) hoping it will make the stitch smaller and closer to each other, as well as adjusting the string tension dial. But nothing will work. Does anyone know what the problem could be? Could it be the needle itself? Please help, i’m at a loss.

    What is the Make and model of the machine??

    Needle should match fabric E.G. for knits you need a ball point or stretch needle.

    What fabric are you sewing? Does it happen on all fabrics?

    Could be many things, hoping it is something simple.

    HI Patti, thanks for answering. It’s a chinese model, SunStar KM-250A. The book enclosed is written in very poor english, so it’s difficult to understand. This problem is happening with all different fabrics. I’ve noticed today that not only are the stitches long and poorly spaced, it also tends to pull the string and “bunch” the fabric. Best way I can explain it. The anchoring stitch is so far apart that the slightest of pulls breaks and unravels all of the stitches. I’ve tried changing the needle and it’s direction (The neele is rounded on top) but still the problem presists. There are only 2 knobs for adjusting. One for stitch length/width and the other for tension. That’s so far as I know…. Is there any other point on the machine that I need to adjust?

      Hi, Not that familiar with that one but , check to make sure that that your drop feed is not down, think that has a drop feed.

      It may need to be serviced timing may be off.

      Let us know how it goes hoping someone has more information.

    Finally, gave in and brought in a professional. It turns out that since the machine comes in pieces and is assembled in the stores, the screws underneath were not tightned properly. The knob that adjust the length was turning on empty so to speak. And almost everything else was getting ready to fall apart. It’s all fixed now, and I’m back to ruining fabrics! L Beginner, like I said, but I’m trying. Thanks for your help Patti.

    So happy you got it fixed, you must be so relieved, that looks like quite a machine I researched it a little.

    They have a few manuals online about the parts and assembly maybe instructions they were Free PDF’s.

    Thank you for getting back to us, this may help others who may run into the same problems you had.

    Wishing you much success in your new sewing adventures.. We were all beginners at one time.. Patti
