Actually somewhat simple. You need to remove it from the machine. To do this, remove the nuts attaching it to the head. I remove the slider cable by removing the 3 screws at the top. Next, remove the second throttle cable by taking off the plastic plate on the side and disconnecting the cable on the inside.

I placed it on some clean cotton cloths and removed the bowl, jets, choke plunger, diaphragm and ran choke cleaner through it all. I would recommend that you replace the float, diaphragm, and rubber gaskets. Check the slider for wear and replace this if it is worn.
