Rebuilding quadrajet, stuck secondaries

[dkraven]

Some of you might have seen my other thread on my engine dieseling. Decided to just rebuild and clean the carb before tuning and I'm glad I did as whoever did it before did several things wrong. This is my first time doing this but been making notes and watching videos. Got the whole thing apart but the secondary throttle shaft isn't moving at all. Is this a novice thing I don't know about or should these not be stuck like this?

They should completely open with full throttle. Usually secondaries don't need service during a rebuild. Try penetrant on the shafts and slowly work them until free.

Starting with the pb blaster, also wondering if they'll loosen up when I dip the bottom plate

edit: so far no luck with the pb blaster or light hammering on the end of the shaft, it's pretty damn stuck

Butane torch finally freed the stuck shaft, now I can put it back together.
