Well, are you sure the high speed needle is seating properly and not damaged? How about the thick nozzle gasket, is it is place, in good shape? If the nozzle gasket is missing/messed up it will cause the engine to run rich at high speeds…Turning the high speed needle all the way in compensates for the extra fuel leaking into the high speed nozzle well…
