"One-way" fuel line valve..?
Here's what says the FSM about ECS carburetors :
I don't know what's a "bleed device which prevents build-up of pressure in the fuel line between the pump and the carb", but if it helps for hot startings*, maybe it makes cold starts more difficult.
* It's true that when my engine is hot, it starts instantly without touching the gas pedal.
Engine cold and choke on, it needs a series of three crankings of about 5 seconds each (with 10 seconds interval between them) to start.
Maybe that I'm too much demanding and such starting procedure is normal :)
