Troubleshooting is always the same: Start with something good and move forward until you find something bad, then go backwards and forwards until you're sure of where the problem is.
Assumptions: "spark @ the points" means you see an arc across the points when they open. "nothing @ the plugs" means you don't see an arc if you remove a spark plug, plug it back into its lead, ground it and crank the starter.
