None of that addresses the WFO problem. Any chance the carb/manifold is getting too hot under load so as to boil the fuel? (exhaust flow through the intake manifold crossover because of an exhaust restriction including the heat riser valve not fully open.) That's the only thing I can think of that hasn't already been mentioned.
