Consew 118 needle bar adjustment

[Mark59]

I purchased a Consew 118 and it won't stitch.  It's obvious from cleaning and observation that the needle is very deep when the hook passes above the needle.  I have the operator guide but not the service manual.  It's obvious I need to adjust the needle bar height and timing but I cannot find any documentation.  Plus, I can't even locate the screws to adjust the hook timing, it appears to be one factory assembled unit.  Can anyone guide me to a service manual, or video, or share any information to help me adjust the needle bar and timing for a Consew 118?  Thank you very much for your help.  Mark in Colorado. PS:  One picture shows how deep the needle is and the hook is at the very top where the uppper notch is.  The other picture shows the back of the hook assembly where I thought I would find the timing screws, but there are none.  thanks again.
