This is a 25hp and I have already rebuilt carb and installed new plugs and wires and 2 new coils,
she idles ok and has smooth mid range but WOT misses and smokes bad, hurts to hear it. Replaced with new oil and gas in tank (non ethanol) could it be the control box? Anyone got some info? Im ready to give up and go to the dealer, but I dont have $ for that right now.

I guess everyone is stumped? Does anyone know about the fuel pump gasket and diaphram being transversed and making a difference? I have a wmc carb.
