Check the 2 small wires from the pickup coil to the ign module.I have seen them crack inside the insulation due to the back and forth movement of the vaccum advance.They usually break closest to the pickup.Give them a little tug and see what happens.Also check the pickup coil resistance with a DVOM.Cant remember the spec but it should not be open ckt. Hope this helps..
