Hi Simon
The crossflow generally has a mechanical fuel pump so it takes a number of revolutions to pump the fuel to the float chamber where with standing it has evaporated.(Seems to be worse with modern fuels) A solution is to plumb a electric fuel pump in parallel which can be switched on before starting so filling the float chamber prior to starting.
Saves a lot of drain on the battery as well.
Hope all the suggestions help.
