Mags are pretty simple. Condensers seldom give you trouble, check the points making sure they are gapped correctly. I don't know what resistance reading you should get across the primary coil windings but if you don't get some reading you have an open circuit and the coil is bad. There's a remote chance that the permanent magnets in the rotor may need to be remagnitized - if there is a shop that still does that.
