T-5 to flathead won't shift into gear with engine running.

[Init1]

Using a bronze bush. I can see the disc turning through the inspection window in the bell housing when I put a crescent wrench on the throw out shaft and move it all the way forward
With the right rear wheel off the ground and me spinning it by hand and the trans in a gear.
And the engine off. I can see the throw out moving normally forward when I depress the clutch.
It could be the input shaft is touching the end of the crank causing it to spin all the time.
Good thought.
Any ideas?
