HI, this is a first post for me , although I have been reading the forum for sometime and it has been a great help, so thanks. As one of my interests is WW 2 military stuff I repair a lot of old leather equipment , but also make new parts when needed .I have now got a Singer 211G358 sewing machine, I know it's not a walking foot but as it will mostly be used on thinner leather and canvas, it seems to cope with this well. I have gone through the machine using a lot of advice from here but I am having problems with the stitch length/ reverse. This is a large bobbing machine and it it supposed to have a 10mm maximum stitch length, but It will not adjust to this size, also when it is sewing the reverse lever it moving up and down about 3/16 is this normal? I forget to say following more advice from here I've fitted a servo motor. Any help with this annoying problem most appreciated thanks Pete.
