Mechanic Q: 1980 CJ5 Jeep – inline six 258 Staring problem: Carb?

1980 CJ5 Jeep – inline six 258 Staring problem: Carb is getting fuel, spark is going from the pick up coil to the distributor cap – but no spark at the plugs. Replaced, distributor rotor and cap (which were very new anyway). See no holes / leaks from the vacuum hose attached to the distributor / carb. Wires & plugs have less than 200 miles on them. I’m stumped – any ideas?
