I picked up a 69 Quadrajet that is in good shape and complete. It may have been cleaned and left on a shelf for some time. The throttle shafts are stuck, the choke shaft is stuck and the rear two screws that on the air horn seem stuck. Idle screws are free and inlet threads are not stuck or corroded away.

I would like to save the carb without breaking, hammering, cutting. Any advice on how to free up the stuck shafts and screws? The body and air horn aren’t corroded and seem to have the original coatings in good shape. The throttle base is clean and not damaged or showing any major corrosion.

What’s the best way to save something lie this?
