Howard, I've replaced dozens of these and now automatically look in to check the cords. When you have repetition problems and slow hammer return, you know what it is. Yamaha told me it only happens in my part of the world. I do agree that it is what the cord is made of and not the corrosion of the spring. The cord turns to POWDER! On a warranty replacement I was told that I should have been able to do the job in less than half the time I estimated and there is no consideration of the need to file the hammers for correct hammer/string alignment. I should also say that I have not seen this on pianos built after about 1980 (?) and I suspect that they found out what the problem was. A jig can be made to cut and glue new cord on the existing flanges, but I usually just replace.
