G'day folks,
This past ODK thread has good info on the Victa 3D [aka Model 4] carby; Carby Thread

It's a bit different to the 3F/3L carbies, as it has a slide/needle setup to give it variable jetting.

The 3S carby was a modified version of the 3L for the 160cc engine, with a larger venturi diameter and jet size than the 3F/3L.

Cheers,
Gadge
