The slow jet is screwed into the carburetor body in the bottom of a hollow well . This jet controls the fuel flow as much as 1/4-throttle.

The emulsion tube (A) is threaded into the bottom of the carburetor body. The main jet (B) is screwed into the end of the emulsion tube.

The drilling of the slide (optional) the diaphram assembly and the different main jet needles. Under certain conditions like cold temps and low RPM's this operation can cause a pop back from the carb from the slide opening too fast and leaning out the mixture.
