It's mechanical, mine was binding and I disassembled it and lubed it.

Twenty five years lets a lot of crud get in the mechanism.

I got fed up with mine.
I removed the big spring.
Problem solved.

From your description it is working the way it is supposed to. Go figure the minds of Benz.

You are missing one of the springs on one or both of the ratchet mechanisms.

You must pull the lever back up to lock it at the level you want.
