To test for this being the problem, hold the choke blade fully OPEN and check the throttle action under the hood.

The lockout is on the passenger's side and is not difficult to disable. The secondary throttle blade lockout, AND the secondary flapper lockouts on the earlier carbs are removed or disabled as standard procedure whenever we work on a quadrajetjet.
