Volvo 122S SU HS6 carburetor needles

B20 engine, K-CAM, 0,8mm cylinder head gasket, 2x SU-HS6: 166Nm@4000rpm, 113HP@5600rpm

SU HS6 needles: Current setup with RN needles too high enrichment >> 3000rpm, Lamda = 0,78 – 0,82

I will modify to KD for less enrichment at fullload, ~ Lamda 0,85 – 0,9 2-4HP more power
