Sounds like the low end needle is too fat.
Lean the low end needle a bit more till the idle stays high after a WOT pass. Then turn down the idle with the idle screw. When your idle is consistent check you high speed needle. It might need richening up a little bit after this.
Edit:
If you mean stuttering / machinegunning when your talking about a high idle after WOT then your low end needle is too lean (possibly high end needle aswell): richen it up a bit.
