It should have the choke pull off on the right front and a vacuum break on the right rear.

How do you know the secondaries aren't opening?

Are you talking about the secondary throttle blades or the air valves?

Are you talking about the throttle plate valves or the upper air valves? If the lower, if the choke is not adjusted correctly or the rear dash pot and linkage is missing the lower tv will not open.
