G'day Folks

The throat size of the carby also has an effect on the fuel, the later carbies for the 202/3.3ltre motors have a much larger venturi than the early "Grey" motor Holdens (138 cubic inch) Landrover 2.25 =139ci, the ideal main jet for a Stromberg BXOV-1 for a Landy is a 49 or 50/51, should be available from one of the Holden Specialist Restoration Coys, "Rare Spares", or Harrisons Holdens comes to mind it might be worth getting on the "Old Holden website and try to source a Jet or a complete early type (FJ--EJ) or no later than a HR.

I personally recommend a Zenith 36IV type (2.25 from 1967-on)as they are a quite reliable carby, Note: mixture adjustment for them is-- OUT = Rich, IN = Lean, THE OPPOSITE TO A HOLDEN STROMBERG

Hope that is of some help
