Did anybody give consideration to the pressure feed to the fuel tank pushing fuel to the carb (and the carb spray bar). Yes, we know that the pressure drop pulls some of the air fuel mixture down the intake throat, but could not the pressure feed also contribute to fuel spit back? I mean the flow is generally unregulated (exception to Iron Bay and Cline systems) and rises with the increased pressure input to the tank. So that the worst of conditions are at max revolutions - max flows, max pressure into the cart needle valve, etc.
