Hi all,
i had the same issue on my 37 when i bought it. when was hot if i stop the engine i was obliged to pump several time with accelerator to run... I measured temp at fuel pum and carb and found more than 60°C.

I solved the problem by closing the two holes in intake manifold with 2 little metal sheets and adding a big seal (5mm) between the carb and the intake manifold.
