And just as important, which chokes (venturis) does it have? A weber DCOE 40 with 27mm chokes will require different jetting than weber DCOE 40 with 32mm chokes.

Baseline jetting
Quote:
Conversion equipment jet setting Datsun B110 (A12) - single 40 DCOE 2
Choke size 27
Aux. venturi 4-5
Main jet 1-10
Emulsion tube F7
Air corrector jet 1-65
Idle jet 0-50 F9
Accel. pump jet 0-50
Accel. pump inlet valve with ex. orifice 0-50
Needle valve 2-00

Weber DGV Tuning has three sample jetting specifications. Unfortunately two are missing the venturi size.
