Well, that' different. I have never seen such a petcock. I suppose that they are relying on the lack of intake vacuum to take care of the off function. At least you have the On and Reserve settings to allow for fuel management.
I could see where the Prime position would be handy - just don't ever leave it in PRI after the engine starts.
