It might help and I highly doubt that it will hurt. Do give it a bit of longer lasting lubricant after.
My guess is that you have a worn out spring or detent, but it is truly amazing what refreshing old lubricants can to sometimes. Most greases don’t exactly perform properly after a decade or two. Even my still in the tub Park grease separated after less than that.
