Do any of you guy's know if the idle air bleeds on the secondary side perform a bleed function on a vacuum secondary carb.,The reason that i need to know is that i am going try out my QF 780 carb. next week and it is idling to the point of stalling (lean)and i had no control of the idle mixture screws,so i notice that the air bleeds on the secondary side were smaller than the primary side so i swapped them over and now i have some control of the mixture screws and it idles alot better without stalling.
