Thanks to Matt Cooper from eurocarb for providing the following information describing the differences between the various VHB carbs.

VHB was the original carburetor for all 20 mm to 30 mm sizes. Then Dell'Orto changed to VHBZ for 20 mm to 26 mm carburetors and VHBT for 27 mm to 30 mm carburetors. VHBZ and VHBT have a separate needle and seat.

The following diagram was gleaned from the Moto Guzzi Workshop Manual.
