Before I try anything I'm going to talk to Cambridge - but I thought
maybe I could get some good advice here. A little oil sounds like a
good idea for starters.

We used the oil - bent it straight or at least eliminated the orbit -
but it still won't return when pushed in. It's usable because it can
be manually pulled out but it will have to go to the factory to be
properly fixed.
