The contact of the rotor wiper on the tuning cap may have a spot of corrosion where it sat for years. Using a blade of stiff but very fine sandpaper, slip the paper under the contact blade with the paper side facing the blade. Gently pull the sand paper through. Do that to both blades at the point of the "flat-spot"
