I have scoured the web, and here, but I really can't find a good guide for ensuring mtg timing is right, and threading the bobbin correctly. I downloaded the user manual that is often linked on this site, and it's really vague to me. I'm a newbie, but I really thought I had the mechanical aptitude to figure this out. Any help would be greatly appreciated. When I run it slow by hand, it won't pick up the bobbin thread, and the needle thread gets wound up on the bobbin carrier. I believe I have my needle height set correctly by the manual, but I could certainly be wrong.
