So did you set the needle valves with a vacuum gauge? I think most guys say they can hear when they are set correctly, but a vacuum gauge held to a hole on the exhaust manifold can make setting it/them more accurately.

Joe, don't you mean a vacuum gauge connected to the intake manifold? There is no vacuum present in the exhaust manifold. You should be adjusting idle mixtures to the maximum vacuum consistent with the leanest mixture.
