Now here's something... my 15-91 did a fabulous job on FMQ last night. So solid! However...
Once I let up the gas on the pedal, the needle goes up and down about 5-6 times. Also, when I load the bobbin, the bobbin winds really fast and neat, but the needle goes slowly up and down at the same time. Any thoughts?
I think I need to go see an OSMG. The pedal goes 100mph or 0. No in betweens. I think I need a rewire....
