The 2000 130 has an adjustable Idle mixture screw. Does this circuit get cut out once the low speed and or high speed jets kick in?

I ask because I have adjusted my carbs. At first i went too lean and the motor would stall out if I banged her down. So richened each carb about 3/8 turn out and started over. Ended up going 1/8 to 1/4 in on each and response seems good. Has not cured my original issue albeit a small one. Between 1000 and 1500 rpms it sounds as if I am dropping a cylinder. I cannot tell if it is starving or if it is loading up. Once I break that 1500 barrier smooth as a kitten on up to WOT. Is it possible I am looking at an intermediate jet issue or an adjustment on idle circuit. Carbs have been rebiult, floats are correct and seating.

Have someone drive, you squirt fuel into each carb throat when its dropping a cyl, you should be able to isolate the clogged carb.
Or re-do the lot.
