I recently found a too-good-to-resist opportunity on a Singer 20U73, and I bought it. Now I'm trying to train myself on the great differences between an industrial amd home machine. My biggest problem is this: when I depress the pedal to begin sewing I have to push it almost all the way to the floor, then it suddenly takes off almost wide open. Getting it to start more slowly seems almost impossible. It has a clutch motor. The book says it's a "tailor shop/drapery machine" so I'm almost certain it's designed for better speed control. Are there adjustments for this? I wanted to ask before I start randomly turning bolts and such. Thanks.
