The newer weber needle valves are junk with a large proportion leaking out of the package. You need to put a vacuum gage on them and go through a bunch to get a good set. I custom made some in order to get acceptable sealing, large enough flow size and light enough balls. Your high fuel pressure at idle will also probably be a problem.
