Answer
Hi Sean,

I cannot see what you have to work with. My diagnosis is limited to what I read.

Check ignition breaker point gap and ignition timing and adjust accordingly.

Inspect and clean point contacts.

Check that points assy. is not grounding.

Check conductors for continuity and condition. Check connectors for clean and tightly fastened connections.

Inspect spark plug- clean or replace accordingly.

Check kill switch for clean, corrosion free contacts.

Check output and continuity of charging/exciter coil.

Respectfully,
