    I think it's pressed in from venturi side? After you remove slides, this gives opening for emulsion tube to move into. First, remove jet. Then take screw with same threads as jet and turn into emulsion tube. Leave about 5mm between head of screw and carb-body. Gently tap screw-head with hammer. After it's loose, use blunt tool to push through slide opening, ball-end of Bondhus allen-key works without scratching.

    * note: look on side of carb-passage that holds emulsion tube. On some models, there's tiny screw that holds emulsion tube in place. Remove that before pressing emulsion tube out.
