On the hydraulic flaps, does the position of the silver pump handle
have any bearing on whether or not the hydraulic pressure leaks out of
the flap, once they are extended? (The POH doesn't say that it does.)


Yes. That's how you retract the flaps.

There is some mechanism underneath the instrument panel that has some
adjustment for the Positive Control. What does it do, exactly?

I don't recall anything at all like that in either the '68C or the '65E
models with which I have experience.
