proform race carb / Idle trouble

after reading some more stuff it seems that i´m wrong - the more out the idle mixture screws are the more rich is the idle mixture. So in this case it needs just more fuel at idle - solution is to reduce the size of the idle air bleeds?

according to the data sheet of the carb it has got "70" air bleeds in stock condition. I just checked it, there are "75" bleeds in the primaries, "73" air bleeds in the secondaries. What do you think, make air bleeds smaller?

Does it make sense to use different sizes in primary and secondary?

I don´t have smaller ones here or i had i tested before.
