Kevin, in general, the steps I take with a sticking throttle would be as follows:
1) Compare your linkage setup to the parts manual - do you have all the correct pieces? Especially verify that you have the correct return springs and that they are connected in the correct locations. I always stay away from aftermarket return springs -- get NOS ones or good used. Are all the little clips that the springs anchor to in place?
2) Disconnect the linkage from the carb, and make sure the various linkage on the carb itself works freely.
3) With the linkage still disconnected from the carb, see if the rest of the linkage works freely. If it doesn't, one by one disconnect each linkage piece to see if the binding frees up. Go all the way back to the pedal. Check all the joints for wear, signs of binding, etc. Repair/replace as required.
4) Is the linkage rubbing on something that it shouldn't be rubbing on - non-stock parts, engine not in correct location due to bad engine/trans insulators, etc?
5) Properly lube and replace all components.
6) Perform any linkage adjustments per the Shop Manual

I'm sure that Ross and others that have specific experience with '54s will chime in here. There may be common wear issues or even design issues that were later addressed with Service Letters. Unfortunately, I don't have much experience with Packards (yet!), but just tried to lay out how I would generally troubleshoot a sticking linkage issue.

Keep us informed on what you find!
