Multi-fuel carburetors and related methods are provided for a combustion engine. A multi-fuel carburetor can include at least two fuel nozzles for providing fuel from a fuel source to a carburetor barrel to produce a mixture of fuel and air. A fuel control device movable with respect to at least one of the fuel nozzles can be used to selectively adjust the amount of fuel that can be drawn through that nozzle, thereby desirably adjusting the air/fuel ratio of the mixture produced in the carburetor barrel.
