I went back and watched the video again. You may have that post grounded, hard to tell. But with power to the other post on the solenoid, it should be starting or at least clicking the solenoid. Is that a new solenoid? If no click, I would say that solenoid is bad. Did you ,by chance, clean the large ground wire at the front lower right side of the engine. It is short, goes from the engine to the frame.
From what I can see, you are doing things correctly. Something (solenoid or bad ground) is not right.
