Every time a switch (in this case, a set of points) opens and closes, RF noise is generated. Add that to the original, uninsulated, unshielded copper spark plug wires and you have an antenna emitting high energy noise into the engine compartment. If you want to run modern electronics, you MUST remove the noise. Shielded spark plug wires and a modern style cap are a must. I know it's not for the purist, but most of your problems will go away...
