Probably just needs the advance weights and pins lubed up.
Make sure the springs are not broken etc.
If it is a GM dist it may have white nylon pin bushings
They are available from NAPA.
GM hei distributors suffer from spark ionization....that brown dust.
Drilling two 1/4 in holes in the back side of the cap cures that.
Vac advance should be conected to full time manifold vac port.
