Perhaps I should only use word "idle" when it relates to "idle-speed screw". Yes, max RPM, when adjusting mixture-screws. But actual RPM number is not relevant because we don't know what setting of your idle-screw is. When fully warmed up, idle-speed can be 1300 rpms, or 1500 rpms or 2000 rpms. Actual number is not relevant when starting this adjustment, only at end.
1. first, you adjust mixture-screws to give highest-RPM
without touching idle screw. So you may start at 1478 rpms, then adjust one mixture-screw and it will vary from 1435 to 1505 rpms. Fiddle to get 1505rpms. Then add 1/8th turn.
2. Then do other carb's mixture-screw and you may have range from 1505 to 1561rpms. Highest speed achieved is 1561 rpms. Then give it 1/8th turn more.
3. Now, finally turn idle-screw adjustment to give 1300 rpms idle-speed.
