I'd look at where the throttle plate is, in relation to the progression holes.
You want it to start uncovering a progression hole at the first movement of the throttle. I think it is possible to setup idle by keeping the idle bypass screws shut and opening the throttle to the first progression hole, but you've then got a fair way to go to the next progression hole.
Correct way is to have idle on completely closed throttle and idle air supplied by the bypass screws.
