Got a single barrel rochester from 1963 and having some issues. The choke was disabled by the previous owner by removing the choke pull-off rod and zip tying the linkage open. Now the choke plate is jammed full open and won't close. It's a divorced choke and everything is working except the choke plate won't swing closed. It's like the linkage is on backwards or something and preventing it from moving the way it needs to. If anyone has any knowledge of these carbs I'd appreciate some ideas. I can grab some pics and info off the data tag if it helps.
