Ok i tried a different needle, 90/14 and my thread is a 30 weight i managed to do almost a whole row before i got a snaging mess. i can hear when it happens so it seems like the bobbin is doing a spin. my quilt top is supported and i slowed down my machine, i can see on some of the curves i have little eyelashes. i am still waiting on the bobbin washers i hope that helps.
