When I got the machine it was so dirty you could not turn it. I cleaned and oiled it and it turns free now but it breaks the threed at the needle as soon as you try to sew.
This would probably be caused by the top thread tension device being too tight, dirty or gummed up. If the machine was really dirty then good chance the tension device will be gunked up too.
Have you cleaned the top tension device too?
I'm not really familar iwth the Consew but on domestic machines where the tension device is two metal discs with a screw/dial to tension them, you turn the knob down to zero to open up the device as much as possible, then clean between where the thread runs by flossing it with a selvage edge of clean fabric. If you can do its and black stuff comes onto your fabric, then keep cleaning.
You may want to dip the fabric into denatured alcohol first, this will help degum the tension discs too, this will help clean the gunk off the metal.
