1. Please stop running the engine at WOT.
2. Do not free rev (neutral or Park) more than 1800 RPM until you have got it running right.
3. Try to follow advise laid out here and in most older automotive books. Test the basic engine first (Compression), then check ignition (which seems like you have covered), then fuel supply and delivery.
4. Note the intake manifold. If it's a stock dual plane, half the motor is fed by one side of the carb, (2 outers on one side, 2 inners on the other). This can be the reason that half the cylinders aren't firing. See if the pattern matches. If so, determine which side of the carb is questionable. Also check for vacuum leaks that may affect one side. PCV and Brake Booster are common. A small vacuum line usually won't cause this.
5. Understand that the reason people do things in a certain order is through experience and training. It may seem like they are crazy doing harder things first and that you want to check stuff in a different order (no tools or easier). There is a method to the madness.
