Verifying Spark and Fuel to the carb is a good start. So other things to check would be as follows:
1. Adjust the valves
2. Compression, pull all the plugs (clean and gap them) and run a compression test
3. Ignition - verify TDC for plug #1, pull the valve cover, rotate engine until both #1 valves are off cam (closed) and cam mark lines up with oil bar and Flywheel TDC mark is lined up in view hole above starter.
4. Verify that rotor is pointed at #1 spark plug lead on cap and leads clockwise are in proper firing order.
5. Turn engine over until points block is on the highest point of distributor shaft cam and adjust points gap to .016"
6. Reinstall rotor, cap, spark plugs, spark plug/coil lead(s)
7. Slightly loosen the 10mm nut on the base of the distributor so you can turn it clockwise or counter clockwise with some effort.
8. Spray a shot of starter fluid down the carb throat (open choke flaps).
9. Have an assistant try and start the car. It should fire and run. If it fires and dies, you are just running on the starting fluid and the carb is not working correctly, (clogged idle jet, float adjustment, etc.). If it does not catch (fire) while cranking, the ignition timing maybe off, so you can slowly turn the distributor back and forth while your assistant cranks it over to see if you can get it fire.
