F or G, huh? I tried both a NEDW and then a NEDH. As I recall the H felt a little thick off idle when paired up with a 42 and the AS in the 1.7 to 2.2 range. It ran fine 80% of the time but exhibited a very different behaviour when you got the engine real hot. That's when the idle got flaky and it would feel real lean. Felt like it had an air leak. But the CCK needle back in and the hanging idle went away.
Maybe the needle jet is trashed (it is 12 years old) and that's contributing to the difficulty in tuning.
