Singer 111w155 stitch length issues

[cadet4x4]

I'm searching old threads to figure out why  my 111w153 longest stitch is 6/in. I've reset everything according to Uwe's videos ( I would be sewing without them). Something caught my eye here above "eccentric gib locking screws weren’t in the groove" . 

Is there a video or diagram showing this adjustment? 

 

Thanks

Clarifying here...are you able to adjust the stitch length? Meaning can you adjust to go smaller than 6/in ? 

When making the adjustment toward longer stitches, does the adjustment screw stop?

When your needle lands on the material, what is the motion of the feed dog? Ideally the feed dog is stopped front to back motion when the needle lands. Just wondering if you are losing some traction by something else being out of time. 

Perhaps a video of your feed dogs working, and photos of your  stitch length regulator?
