Sounds like you need to tighten those packing nuts a bit so the needles hold their position. If the low speed packing nut is loose, air might be drawn in through the nut causing the engine to idle lean.
You mention that the high speed needle needed to be just about closed completely in order to run OK at high speed, is this correct? Did you remember to reinstall/replace the nozzle gasket? The nozzle gasket is kind of a thick donut looking gasket that fits around the brass nozzle that threads into the carb body. The original nozzle gasket was probably cork and fell apart when you removed it.
