Hallo,

The ref-nr. of my original distributor is 0.231.170.229 jfu4.

Unfortunatelly this Boshnr. is not mantioned in 123ignition for Alfa.

B - -
C - -
D, 006-’tuning’ for high compression, ’hot’ cams
static timing 12 degr. ; max. advance 34 degrees
E, Shankle-#4255 another popular curve amongst tuners
steep until 13 degr. @ 1300 rpm, then towards max. of 32 degr. @ 4000 rpm.
F, Marelli S103 & S166 steep until 13 degr. @ 1600 rpm, the towards
