Cowboy CB3200 forward and back Stitch misaligned

[palvim]

Hello All,

I've been reading through a lot of the posts on this forum and it is so informative. Thank you all! It is very helpful to a super newbie like me. 

I'm writing as I just started to get an issue with the front and back stitch being misaligned. As in they don't go in the same hole. It worked fine u til yesterday when I tried to stitch on the fold of a folded belt. I think it might have screwed up something at that point. Now everytime I back stitch, the backstitch goes 2 stitches back i.e. 1 back stitch = 2 forward stitches. Please see the image attached. 

Any idea what went out of alignment or how to fix this? 

Any help is super appreciated! Thank you.

I also read up on one topic that inside foot and the feed dog should meet each other just when the needle is going down on the feed dog. I see that is not the case on my machine. Is this something that is the problem? 

The image attached is exactly at the point where the feed dog meets the inner foot.

Did you make an adjustment to the height of the inside foot before this occurred? If not, loosen the big bolt on the crank coming out the back left side and lower the needle to the level of the feed dog, then drop the inside foot to meet it and lock down the bolt. Maybe your bolt loosened itself.

The feed dog should have risen to the top of the throat plate slot when the needle meets it, but should not start moving back at that point. Set this with the stitch lever in the zero motion position to be most accurate.

Thank you wizcraft for replying. Do you mean the opening on the back of the machine? I am a little lost. Do you mean the bolt on this thick metal bar or is it inside the opening somewhere?

Wrong end! The crank I am referring to comes out the back near the very left side of the head. It connects to the presser foot cranks inside the left end. When you remove the faceplate you can see these parts. I'm not able to go to my shop so no photos from me at this time.

wild guess - is it possible that the machine is just skipping a stitch in reverse? Its very unlikely that the F & R stitch length differ by exactly 50%  (as it seems). Is it possible that it is just a needle / hook timing issue?

Would it randomly miss or consistently miss? On my machine it is consistently doing reverse at twice the length of the forward stitch

Yes,I'll agree that's what it looks like to me too.You might try to tighten your foot pressure a turn or two.

If you turn the machine by hand (slow) you can see if the stitch in reverse is longer or  constabulary is right

(my guess would be you are missing stitches in reverse...)

Here is the video of how I'm trying to do it. I tightened the presser foot tension to at least 3 turns. 

And here is with the bobbin cover off. 

And here is the movement of the feed dog, presser foot and inner foot in relation to each other and the bobbin. 

Appreciate your help very much. Thank you.
