Loose top stitch when in reverse 206 RB4 Consew

This machine works perfectly going forward, but has very big loops on the top side of material when going in reverse. I just purchased the used machine today, so I am hesitant to mess with the tension adjustments until somebody can point me in the right direction. Thanks, JR.

Do you know how to check the timing of your machine? It sounds like a timing problem to me. If you don't know how to check the timing:

take the side plate off, take the needle plate off, take the presser foot off, and put a new needle in the machine. Make sure that the needle is in the lowest position and look at the needle bar for the two timing lines. Locate the top line. Then, turn the handwheel toward you until the top line is where the bottom line was. At this point, the tip of the hook should be directly in the scarf of the needle.

How do i adjust my consew 105 so the stitches do not loop on the bottom?

If the thread is looping under the fabric, it is a top tension issue.

Make sure you are using a new needle and that the needle/thread/fabric are compatible.

Verify it is threaded correctly and that the thread is firmly seated in the tension disks.

If the top thread is still looping under the fabric, then the upper tension is too loose.

The thread on the top side of my material starts looping after 4-5 stitches. I've tried every number of thread tension, and even on 0 it loops on the right side of the material, not on the back.

Check the tension on your bobbin thread. When you hold it by the thread and let it dangle does it just drop down without any resistance at all? If so then you need to tighten it a bit. If the bobbin thread is too loose it can not pull the top thread down enough thus puts the loops on the top side of the stitch.

Have a Consew 206RB-1. Seems within the span of a few hours today that whenever I'm turning while sewing any material, it will drop a stitch. When sewing in a straight line, it's perfectly fine. Can't seem...

It is probably because you need to move slower when moving the material around, as otherwise the thread beneath will just stretch over and make a new stitch. just slow down loads and should work! this probably isnt the right answer but hope i may of helped! :)

My material is not feeding through the machine, how do i set it to feed. it works in the reverse mode, but not forward.

If when you sew in reverse you have big stitches then you will need a shop adjustment if you have made sure beforehand that you have the correct stitch length to sew forward.

If the top stitch is loose, then you need to tighten the bobbin tension: if the bottom stitch is loose, tighten the top tension. Hope this helps. It could also be the size needle and thread you are using for a particular fabric. Different fabrics require different notions.
