These ignition systems need good grounds on both the coils and the power pack for them to work correctly. Rust or corrosion could have worked its way under the ground lugs making for a poor circuit. A quick dressing with a wire wheel or coarse sandpaper should make it good again. With both cylinders down, I’d suspect the power pack ground or a short in the wiring to the kill switch.
