for what it is worth the MGCC did a lot of research on vaporisation of modern fuel in old (XPAG) engines and as I recall one of the (surprising) findings was that the heat from combustion going back up the inlet tract was a really significant factor. Their findings are in the TR Register "TRaction" magazine I believe. I don't have a link I'm afraid.
