just rebuilt runs bad

I suggested earlier, might be a bad condenser. There are only a few component, here

A good coil, and hopefully, a matching resistor

A good strong battery supply

A distributor, with properly opening and closing points

A good condenser.

You can easily check if the points are set, just look at them, and use a feeler. Use a light to determine they are actually opening / closing.

Use a clip lead direct to the battery to eliminate wiring harness problems

If you are sure you have a good coil, good battery voltage, and the points are doing their job and NO SPARK, then its time to gamble and change the condenser.
