Pfaff 145 stitch length issue

[IslandMoose]

Good day

I have a Pfaff 145 I'm 'restoring' and in addition to a timing issue that I can sort, there is a problem with the stitch length selector.  The stitch selector sits at the bottom of the opening and cannot be made to stay in any other position.  Rotating it has no effect.

 

Can someone help?

When I was a teenager my parents bought a 145 and I used it a fair amount until I had my own tools.  The stitch adjustment is just made when the knob is "screwed" in and out.  When you screw it in or out, it cams the handle against the plate screwed to the exterior of the machine.  Really very simple design.  Just look it over. I doubt it's stripped out, they're fairly solid.  It's spring loaded to stay "down"   If you want reverse you have to hold it up in "Reverse."    In the sewing world, not many sew miles in reverse.

Thank you, I will inspect the cam mechanism, it may be worn out as it does not bind against the plate regardless of how far the knob is screwed in.
