Dayle,
We actually took apart the entire machine last night to clean out the tensions and lubriciate well before attempting to sew! The machine has a brand new needle in it and everything is turning very smoothly. She is slow to start and the speed is very touchy, it's in a cabinet with a knee-press which to be honest I'm not used to at all! so the touchy speed could just be operator error. I am going to try re-winding a bobbin tonight and see if maybe the bobbin is not wound properly. If that doesn't fix it I will toy with the lower tension. Do you know which screw that is? The service guide doesn't say where it is, all it says is don't touch!
