            Updraft 
              - Model 267 - Electronic Actuator  
            This 
              model features an integrated electronic fuel system that eliminates 
              all external linkage, brackets, belts and pulleys. In addition, 
              the internal bowl venting minimizes the effect of air cleaner deterioration 
              on this carburetor's calibration.
