I must assume you're testing auto with film in the camera and a lens
mounted. If so, there is something more serious wrong with your camera as
there is not enough trim on the auto pot to adjust out 2 stops of error.
Next guess would be oil on the magnet, but then your manual speeds would be
bad too.
I stopped taking in the F as I can't get any parts for it, and in a lot of
ways is a dog to work on.
