Sorry if I was a bit heavy-handed there Tank, I was confident you could handle it and I did want to make the point before you lost confidence in the repair process. Note there are two types of seat used over time on that carburetor: a soft one that you pull out with a small hook, and a hard brass one that you have to tap a thread in and then pull out with a screw. Since you moved the one you have easily, it sounds like it is the soft one.
