Glenda,
I've tried the foot placement you mentioned. Left foot still got ahead of the right so my two foot treadling is at best awkward, at worst unworkable.
The belt on this machine came from another treadle that I put the aquarium belt on as an experiment. It fits very nice. No problems there.
And the 9W-7 rotates backwards from other Singers. The hand wheel rotates away from you to sew, towards you to break the thread and snarl up the bobbin. LOL
