Once the velocity stacks, the filter screen and fuel filter have been removed from the carb top, remove the eight screws holding the top to the main body. Below that, remove the gasket to expose the inner workings of the carburetor. Shown here is the float bowl in the middle; nearest is the main jet stacks on either side and the idling jet stacks on the outsides. To the right of the float is the accelerator pump, and facing into each auxiliary venturi (called boosters) are the pump jets.
