The Pfaff 545 thread tension is acceptable for forward motion through put .........but notices the
tension changes a bit (noticeable) when using reverse.
It is the only machine in my group doing it - the Pfaff 1245 tension doesn't change during a shift
in sewing?
I minimized this issue on the 545 by tightening the upper thread tension, but still have a difference.
Why would the tension change in reverse?

Some guy named Doyle asked this same question back in 2016. :-)
