Product Details

Edelbrock's AVS2 800 CFM Carburetor #1912 with Manual Choke delivers exceptional performance for high-horsepower small- and big-block engines through advanced Annular Flow Booster technology. This innovative design provides superior fuel atomization with near EFI-like drivability and instant throttle response.

Key Features:

  • Annular Flow Booster technology with eight equally spaced orifices in booster rings for refined fuel distribution and atomization
  • 800 CFM airflow capacity specifically calibrated for high-horsepower applications
  • Manual choke system for precise cold-start control
  • No power valves to blow out—unaffected by engine backfires
  • Tool-free metering rod and spring changes in seconds without removal or fuel draining
  • Two-piece ease-of-tuning design allows float adjustments without carburetor removal
  • Qwik-Tune Secondary Air Valve for limitless secondary circuit calibration with hand tools
  • Updated primary and secondary booster clusters optimized for modern fuels and octane levels
  • Superior tune stability—adjustments stay consistent for reliable long-term performance
  • EnduraShine finish resists corrosion and maintains appearance
  • Designed, manufactured, and calibrated in the USA

The AVS2 eliminates flat spots and dramatically improves throttle response in the low- to mid-RPM range while maintaining the top-end power Edelbrock is renowned for. The unique ability to "hold a tune" means your calibration stays consistent, providing predictable performance without constant readjustment. Perfect for street performance, muscle cars, and high-performance street/strip applications.
