Weber IDF Complete Carburetors

The Weber IDF dual-throat downdraft is an all-out racing carburetor. It is a great choice for many applications ranging from modified VW-based engines (a single IDF for a mild street VW or twin IDFs on a Super Vee or radical VW drag engine) to smallblock Chevy engines (a set of four IDFs give a V8 engine terrific power with a vintage look). The IDF is supplied without a choke mechanism, which means better airflow at the expense of cold driveability.
