No spark

The problem is the magnetic pickup up is out of adjustment ...do people just tweak them with a pliers?
How do you know that is the problem. No you don't just tweak them. Do you know how to set breaker points? The reluctor gap is set the same way. If you look down in there is a screw to clamp one end of the assembly, with a sort of slot. You slightly loosen the screw, preferably using two screwdrivers, one in the adjust slot and one on the screw. Move it just a bit, re-snug the screw and see where the adjustment is.

You MUST use a feeler and you MUST check it that the reluctor/ pickup do not mechanically collide WHEN THE VACUUM ADVANCE moves the thing. Best way for this is a hand operated vacuum pump

I highly suggest you find a service manual. Even one for a car will cover those. Go to MyMopar and download the 72 and the 73 chassis manuals. You will have to look both in Dodge and Plymouth, as they do not post all models in all years.
