Edelbrock 1906 AVS2 Carburetor 650 CFM Electric Choke Satin Finish

The Edelbrock AVS2 Series Carburetor #1906 is a precision-engineered four-barrel carburetor featuring a satin finish and electric choke, calibrated for optimum street performance in engines requiring 650 CFM air-fuel flow. This carburetor represents a significant upgrade over traditional designs, delivering exceptional throttle response and fuel economy for both small-block and big-block applications.

Advanced Annular Flow Booster Technology:

The AVS2 features annular flow primary boosters with updated calibration for superior off-idle and cruising performance. Unlike conventional designs, each annular flow booster incorporates eight equally spaced orifices that dramatically improve fuel atomization and metering throughout the entire RPM range. This innovative design eliminates flat spots during throttle transitions, ensuring smooth acceleration from idle to wide-open throttle.

Key Features:

• 650 CFM capacity ideal for street performance applications
• Electric choke for easy cold-weather starting and operation
• Annular flow primary boosters for improved fuel atomization
• Satin finish for classic appearance
• Both timed and full vacuum ports for ignition advance flexibility
• Compatible with dual-plane and single-plane intake manifolds
• Pre-calibrated with .101 primary and .098 secondary metering jets
• .070 x .037 metering rods included
• Orange (5" Hg) step-up spring factory installed

Application:

The AVS2 #1906 is engineered to work with a wide variety of intake manifolds including Edelbrock Performer, Performer EPS, RPM Air-Gap, Performer RPM, Torker II, and similar designs from other manufacturers. The improved fuel metering characteristics make it an excellent choice for street engines where drivability and fuel economy are priorities.

Installation Notes:

Carburetor stud kits (Edelbrock #8008 or #8024) may be required depending on your application. For applications requiring a black finish, Edelbrock offers the AVS2 #1906B as an alternative.
