Check that your points are at 12 to 14 thou. and then most of the time its the coil that takes a crap and arcs to case. I have had to replace a few of them before i went heat exchange. I have a mag with upgraded pulley and it makes it not work so hard slows mag speed seemed to really help mine. It arcing somewhere you will just have to inspect coil for cracks or black lines where its jumping out of it.
