STAGE I: Rochester carburetors are rebuilt to restore factory performance. They are completely disassembled and cleaned. The casting plugs are sealed with epoxy to prevent leaks. All circuits are sized, calibrated and checked for proper jets, primary metering rods and secondary metering rods. They are then reassembled using the highest quality components with a new float, choke pull off and bronze-bushed throttle shafts.
STAGE II: has all the features of Stage I plus fully recalibrated idle, off-idle, main, accelerator pump and high-speed circuits to match engine modifications such as intake, headers, ignition or cam changes. This carburetor features improved idle, instant throttle response, maximum torque and horsepower for street or strip.
