Just remembered; before running the engine for the 1st time, I made a check on the valve train and found 3 valves slightly out of spec.
Have you checked valve tappet clearances? Just make sure the piston is a TDC on the ignition cycle before you do this (both tappets do not move at that position).
Also, I doubt that there is a mistake on the plug wire assignment - there's a large sticker on the ignition that cannot be put on reverse. The engine will run with only 1 or 2 cylinders (rough, but will run) - no reason to go down this route...
Is the fuel well filtered? Maybe there is a little deposit or something on the high needle seat that obstructs the flow.
Finally, Alex is right: the engine needs a good prime to start. Blow on the vent tube of the tank with the carb @ WOT to basically flood it (fuel should even dribble out the trumpet..). Then close the carb to 1/3, ignition on and crank it up (by hand).
