Hi all! ? for u. I found a sewmor 770 @ local thrift and bought it. It has 2 cords that have wall plugs. Is this correct or has this machine been monstered? There is no presser foot...Should there be? Also one plug runs light and the other makes the mach8ine run really really fast and I don't know how to turn it off or regulate speed!!! HELP PLEASE~! I'd love to keep it but right now it is a runaway diesel.
