Ignition troubleshooting, like all troubleshooting really, requires a methodical approach. Here's a decent methodology:
Ignition Troubleshooting.
Fortunately many of the ignition components aren't terribly expensive and are worthy of general maintenance/replacement anyway. If the wires, dizzy cap, points, condenser, and plugs aren't new, consider replacing them as a good practice anyway. Then start looking at battery (is it fully charged?), dwell (are the points actually opening and closing?), grounds, and other wiring.
If you correctly "flashed" the points then you probably have most components in place. Are you getting spark at the plug when your crank the engine and ground the plug to the case? Sounds like you either need a better mirror or a helper.
