Members Gregg From Keystone Sewing Posted January 16, 2018 Members Report Posted January 16, 2018 Two things that may help; Consew 146 and 199 series need a lot of upper tension. Like any zig zag where the hook timing is being split needle bar height is a critical and sensitive adjustment. Do what is in the book first, then follow the text instructions. Normally, needle scarf comes in high on one side and low on the other. Very common for the needle to be pushed out of the way on one side if this is not done correctly. Often, it's a see touch feel type of adjustment.

Members spotty Posted January 19, 2018 Author Members Report Posted January 19, 2018 Definately not threading in that part of the bobbin case. After much further tweaking it now appears to be adequately zig zagging. I can adjust the width and length and the tensions look reasonably consistent. I'll continue to continue to tweak but it looks acceptable for the most part. I did nothing different except for clean every part with compressed air and wipe clean the tension disks. Quote
