Edelbrock AVS2 1906 Carburetor - 650 CFM with Electric Choke, Satin Finish

Overview

The Edelbrock AVS2 1906 carburetor is a satin-finished four-barrel unit built for street performance. With a 650 CFM rating and electric choke, it balances responsiveness and reliability across idle, cruising, and light throttle. The satin finish adds a refined look to many engine bays, making this carburetor both a performance upgrade and a visual enhancement for daily drivers and weekend toys alike.

Annular boosters and metering

Annular flow primary boosters deliver more complete fuel atomization as you transition from idle to the main circuit, smoothing throttle response and reducing potential hesitation. Eight evenly spaced orifices per booster improve metering consistency across the full rpm range, contributing to steadier air-fuel delivery from idle through cruise.

• Improved off-idle response through refined atomization
• Eight booster orifices support precise metering across the circuit
• Satin finish adds durability while maintaining a polished appearance

Performance and compatibility

Designed for a broad set of engines, the AVS2 1906 works with small- and big-block builds and supports both dual- and single-plane intake manifolds. It also features both timed and full vacuum ports for ignition advance tuning, enabling flexible setup for various cam profiles and driving goals.

• 650 CFM maximum flow offers headroom for many street setups
• Compatible with Edelbrock manifolds such as Performer, Performer EPS, RPM Air-Gap, Performer RPM, and Torker II
• Includes jetting and metering rods: .101 primary / .098 secondary jets; .070 x .037 rods
• Orange 5" Hg step-up spring helps calibrate fuel delivery under different loads
• Electric choke aids reliable cold starts and gradual throttle response

Installation notes and takeaways

Match with a variety of manifolds and consider Carburetor Stud Kits #8008 or #8024 if needed. The AVS2 is a practical upgrade or replacement that can enhance drivability when paired with appropriate tuning and manifold choices. The satin finish not only looks premium but also reduces glare in bright daylight.
