  Was this the first start after a rebuilding, or after a long period of
  Was it running OK before the new points, condenser etc?  Unlikely as it
seems, I experienced three new defective condensors at one time. Let's
hope I bought and destroyed all of a bad run. They sure caused me grief. 
  Have you double-checked wiring to plugs, 1 3 4 2 as the distributor
rotates anti clockwise?
  A timing light clipped to each wire in turn can help identify one plug
that is shorted and not firing. 
  Have you any reason to suspect that the camshaft timing has
changed--new cam, new chain, new pulleys, etc?
  If you are sure ignition is good and valves are adjusted, look for air
leaks in the carb and intake manifold connections.  Once the engine
starts, you should be able to push in the choke within a few seconds of
starting, so (assuming electrics are OK) it could be lean mixture. 
  Are the dashpots filled with oil? 
  Playing the gas from an unlighted bernz torch around the gaskets is a
way to check for intake leaks. Gas that gets sucked in will raise idle
speed. Look for loose plugs in the ends of intake manifold--a backfire
can sometimes pop a plug loose or out. 
  Good luck-two more days of Labor Day weekend to go TD driving.
