Hi Floyd,
Thank you for your observations. I am an absolute beginner when it comes to sewing machines. So it is quite likely that I have made some incorrect assumptions and the reverse or stitch linkage mechanism I videoed is not related to my issue.
I really don't know what things are yet with this machine and did not think it had a reverse mechanism or how that gets engaged.
Thank you to you and all the others here that are assisting with this issue.
I'll have a look later at it when get back from work
cheers
Paul
