This document describes the working principle and features of the O.S. 2B-2CB-D-2CK automatic fuel supply system. The system incorporates an automatic mixture control device that ensures a correctly balanced mixture of fuel and air for the engine at all throttle settings. The device reduces the effective size of the fuel jet orifice as the throttle is closed, preventing the engine from running too rich at low speeds. Additionally, the system no longer requires an airbleed, maintaining maximum suction at the fuel jet. The document also provides instructions for adjusting the system and notes on different fuel and climate conditions.
