The main venturi (often referred to as the choke) is one of the most critical components when tuning your carburetor. Its function is to create a restriction in the carburetor barrel that increases air velocity, which in turn creates the vacuum signal required to draw fuel from the auxiliary venturi.
Choosing the correct size venturi is a balancing act. A smaller venturi provides higher air velocity at low RPMs, offering a stronger vacuum signal and better drivability/torque at the bottom end, but it may restrict top-end power. A larger venturi allows more airflow at high RPMs for maximum top-end power, but can cause the engine to feel weak or hesitant at lower speeds.
This venturi (part number base 72303 + size, replaces older Weber number 72302) is sold individually. Please note that you will need two (2) venturis per carburetor for the DCOE series.
