Edelbrock 1406 whistling

Johnny....I disconnected the choke wire and wired it fully open with a paper clip, and started it up. Still whistles. I put my hand over the valve to restrict the air, and the idle picks up, the whistling diminishes, but it is still there.

After the car warmed up, I reconnected the choke wire and watched the valve...it stays about 1/2 open, and does not move.

Still whistling. :)
