Show original supplier description
The Edelbrock #1901 AVS2 Series carburetor is a 500 CFM, dual-pattern unit designed for small cubic-inch engines used in single-carb applications. It features an electric choke and a satin finish, making it suitable for street, strip, and drag racing use. This carburetor is calibrated for single-quad setups and includes both timed and full vacuum ports to support ignition advance. Engineered for optimal performance when paired with an Edelbrock Performer or Performer EPS manifold, or similar aftermarket intake manifolds, the #1901 offers precise fuel delivery. It comes factory-equipped with .095 primary and secondary metering jets, a .070 x .052 primary rod, and an orange spring rated for 5' Hg. For installation, carb studs #8008 or #8024 may be required. This particular model is not CARB legal and cannot be sold or shipped to California.
