Take apart emulsion tube into constituent parts: main jet, holder, needle jet collar. Note how needle-jet collar is oriented so you can re-assemble later same way. Unscrew pilot jet being careful to not lose spring, washer and O-ring. Might as well replace O-ring, float-bowl seals and float-valves.



Then use soft copper wire of various diameters to poke through all tiny little orifices in all parts. Some people use guitar string to floss out secret passages in carburetor body. Blow compressed air through all circuits and verify you've got air coming out other end.

Here's good site for working on these carbs: http://www.vulcangadgets.com/files/keihin_carb.html
