A few quick checks for fuel and ignition. Make sure you have fuel at the carb. And old fuel pump takes a while to suck gas all the way from the tank. If you don't have a transparent fuel filter up front to monitor, either: remove air cleaner, open choke flap if necessary, use flash-light to look down carb throats, open throttle quickly and you should see gas squirting into throats. Or, pull fuel line from carb, stick in a bottle, disconnect big coil wire at distributor and ground it, and turn over engine. You should have gas squirting out. On ignition front, make sure points gap is correct, cap terminals and rotor are clean, wires are in correct order and perhaps check static timing (at TDC) to make sure its in the ball park.
I've used Quick-Start in the past. A little goes a long way. Sometimes enough to get it firing. But eventually you need fuel flow and healthy spark.
