Perfect for stock or mild performance engines, the Weber 32/36 DGV carb is a progressive down-draft carburetor with counter-clockwise rotation. As a progressive carb it operates as a one barrel most of the time, with the second barrel only opening when more power is needed, or under wide open throttle.  The DGV offers increased performance, trouble-free maintenance, excellent drivability, and in most cases, improved fuel economy.
