You got theLow needle about right,But need to adjust the High needle richer to get WOT right. The idle needle contributes a lot to the mixture at WOT, so be careful there. Any small changes with the L need also changes to H.
I run my engines with air filter. That may be of influence.
The reeds have nothing to do with it, unless broken, in which case the engine will be hard to start and idle.

edit:
The L needle has a very steep taper, so it is very sensitive to small corrections. When the setting is about right, 1/64 (one minute) changes will be about right if you do not want to over-correct.
