Skip, There's an electrolytic cap in the FM discriminator circuit that should be replaced. It's a low voltage cap around 4-5 mfd and will be in the secondary circuit of the last IF transformer. These always cause problems if not replaced. Be careful with polarity, all the ones I've replaced have positive lead to ground.
