HOLLEY 080508S 750 Cfm Square Bore Vacuum Secondary Electric Choke Replacement Carburetor
This carburetor features a vacuum secondary with a metering plate that
has no jets, power valves, or accelerator pumps which makes it easier to
tune than full race carburetors with temperamental secondary metering
blocks and dual pumps. It mixes the right amount of gasoline with air
so that the engine runs properly. It is calibrated for gasoline and
engineered to improve performance.
