are all Qjets with the same CFM rating, for the same kind of engine, the same? Excluding the computerized and new ones? I want to call LORDCO to see if they even have a q-jet rebuild kit. and i'm just awating a carb from James (79stomper) other wise I'd know. anyone know if the parts are interchangeable? and if the rebiuld kits are the same? What should come in the rebuild kit? Any special tools I need? Do I need one of those stands they advertise on JEGS, or shuld I be fine if I support it by little slices of wood? Thanks!
