The HB-14A brings all the Championship technology from our HW line to larger displacement racing engines. The HB-14A has been bored out to a Venturi size of approximately 35mm for use in a variety of high performance racing and competition classes.  It is set up for standard gasoline; for conversion to alcohol, we recommend using EC Carburetors or your local tuner.  Unlike most larger float carburetors, the HB-14A can be tuned while driving through the high and low speed screws.
