The needle valve retainer is located is right inside the carb body threaded hole for the low speed adjustment needle and knob,located on the front control panel . Remove the knob ,unscrew the brass needle counterclockwise till it is free of the threads ,carefully remove straight out. Then look into the opening of the hole the needle came out of. The retainer should be flush or almost flush with the carb body exterior surface.
Your photo shows the float valve needle,which is a different set up.
