freeing a stuck carb

How bad does it look? Or does it look normal?

What worked for me is to soak it in new ATF above the throttle plates. Do not work with used fluid. And just wait 2-3 months. Try to move it back and forth with normal pressure, one day it will very slightly move. Now move it daily, don't force it, be gentle, and a week later it will be free.

ATF is high detergent and it will work, done 7 of them.
