SU Guru needed. B20 Lean Stumble 120-130

Do SU needles fit the Hitachis? Useful if they do. Needles can be selected with many variables but you may need to get the car on a dyno to get good mixture readings across the rev range.
Might be down to timing, carburation problems often turn out to be ignition ones. Check that the advance retard mechanism is free and working well. Again the dyno will be your friend there too.
