Abstract
An improved two-barrel, multi-fuel carburetor. The carburetor comprises a main body portion in which the main fuel bowl is positioned and an auxiliary body portion in which an auxiliary fuel bowl is positioned. All of the fuel and air passages extending between the main and auxiliary body portions extend through faces of the respective body portions that are in facing engagement when the auxiliary body portion is affixed to the main body portion so as to eliminate the necessity for external plumbing. Also, an improved arrangement is provided for preventing the discharge of fuel from the auxiliary fuel discharge under some engine running conditions. The carburetor also employs a simplified accelerating pump discharge that uses only a single accelerating pump discharge tube that extends completely through one of the induction passages and which terminates in the other induction passage and has discharge ports in both induction passages.
