no, lean it out.
If I recall, the low mixture adjustment actually moves the spraybar position.
My old CMB .60 had the same arrangement.
Oh...!
One more thought..... after looking at your photos....
The only thing that keeps the slide in the carb body is the throttle lever. Make sure your throttle linkage does not permit the wire to leave the slot. If it is possible for the wire to leave the slot (especially under vibration with the throttle pushrod shaking around a bit) the wire WILL leave the slot, and the slide will fall out of the carb body (and of course depart the airplane at the worst possible time into thick jungle/grass). In a best case, the slide does not fall out, but you loose throttle control.
One way some of us avoided that ...... drill and tap the slide end toward the high speed needle side. I had a machinest friend do it, and it was a #1 screw. Small screw, washer,locktite installed after the slide is in the carb body. Creates a stop flush on that side of the carb at full travel position. Prevents it from falling out.
it was a good fix. Webra adopted it. The current version dynamix comes like this from the factory.
