1960 series 2 land rover. Problem - idles ok on flat but dies on the slope/hill. Have put new parts in solex carburettor (Float etc). Is it the fuel pump?
Speaking solely from experience with working on and tuning different types of carburetors,mostly racing type cars,a carb engine that dies on a slope is starving for fuel,obviously,and more often than not it's either the float level and drop,or needles and seats.It is critical to measure and set the drop of the floats to prevent fuel starvation,as well as the maximum level allowed by the floats,to prevent flooding out the top.Needles and seats regulate the fuel coming into the carb based on the float level,so they are tightly intertwined with one another.Later versions of carburetors have high flow,and/or spring loaded needles and seats for extreme 4x4 climbing,so that starvation isn't an issue.Check fuel pressure from the pump,as well as volume,Volume is as important as pressure.You can measure volume easily with an empty jug and a helper to crank the engine over while you hold the fuel line into the jug,and watch how much fuel it's pumping.Easy and cheap check,plus you can watch what kind of pressure the pump is developing.6 psi is about the standard for carbs at the inlet.Racing engines can run 7-8 psi fuel pressure.Good luck.
