But if your carb is causing the fuel to vaporise, shouldn't this leave liquid
fuel in the pump?
Perhaps there is more than one problem, first the pump itself (assuming
mechanical) can cause the fuel within it to vaporise, preventing the pump from
pumping much. Second, the carb can vaporise the fuel in the float chamber,
causing all sorts of weirdness to the mixture.
