Margaret,
I don't have that model, but I do have several other White made Kenmores.
First; they rotate opposite from Singers. Nuther words the hand wheel rotates
away from you rather than towards you like the Singers do. No big deal there other than getting used to it.
Second; if it has a spring loaded motor on the back like the other 117s I have do, take a spring loaded clothes pin apart and slide half of it between the motor and machine to keep the rubber drive pulley off the hand wheel. This prevents flat spots. You'll probably have to adjust the drive pulley in or out to get away from the existing flat spots or replace it.
Also here is a Google I did for this machine. The photo section has lots of pics of them.

I wasn't trying to cheat you out of doing your own search, but I was curious what this machine looks like. Nice machine.
