The WOT on has a minimal impact so I doubt if that is not your problem. Does it start and idle OK? If so, I would suspect failure in the vacuum advance system somewhere, the throttle plate is sticking or, the idle motor switch that operates the vacuum advance solenoid in unison with the idle motor is stuck too, like your WOT micro switch. Are the vacuum hoses routed properly? Double check this too. Timing light is a tool that can tell you if the advance is operating.
