Cobra 29-18 Not Working Properly

[TomHu]

When I turn the hand wheel with the presser foot up the needle goes up and down with no issue.

When I lower the presser foot or put something in the way for it to sew (presser foot up or down, it stops working.

I then have to use the side wheel that holds the motor belt to complete each stitch.

9313- Vibrating Presser Lifting Lever
9205 Litfting Lever Shaft Lever
9206 and 9207

In the head of the machine.
When the presser foot is down the 9313 is unable to move the 9205 to complete a stitch.

If I force it with the 9107 then it will do it, but not with the hand wheel alone. It seems like the force to complete the stitch in the head of the machine has been eliminated and I do not know why or how to fix it. 

If you need a better idea of my numbering system please see the manual with diagram link (https://www.springfieldleather.com/cobra-manuals/29-18 Manual.pdf)

 

Any advice, tips, or tricks are appreciated. 

 

Thanks!
