JET Performance starts with a complete disassembly of a hand-selected Quadrajet carburetor core that has been cleaned and inspected. The casting plugs are sealed with epoxy to prevent leak-down into the intake manifold. All circuits are checked for proper sizing and the calibration is checked for proper jets, primary metering rods and secondary metering rods. The carburetor is then reassembled using the highest quality components with a new float, choke pull-off and bronze throttle shaft bushings.
All Stage 2 Quadrajet carburetors undergo the following upgrades: fully recalibrated idle, off idle, main, accelerator pump and high speed circuits to match any modifications done to the engine such as intake manifold, headers, ignition or mild cam change. A Stage 2 carburetor delivers improved idle quality, instant throttle response and maximum torque and horsepower.
