Peggy, are you from Muldrow? We are in Enid. I probably would not be to quick to order the main spring. It is probably not what was keeping it from running. I would clean it first reassemble and try to put it in beat. Usually they will run with set springs, but won’t run the full 7 days. I try not to put new springs in unless they are completely set. I have had to many of the new springs(made in India) break, after being wound two or three times.
