    I'll give you the short version.
    Flip you carb body over from the way this picture was taken.
    Find the brass plug that you can't remove.
    Drill a small hole (1/8") in that plug. You will destroy it and the screen over the needle seat.
    Screw a self-tapping sheet metal screw into the hole you just made.
    Pull the plug out by the screw with the plug attached to it.
    Use a small c-clamp to push the needle seat (in your picture) out the top of the hole you've just opened.
    Order replacement needle, seat, screen, and plug.

    Replace.,..... CAREFULLY.

    Good evening. I am new here. I am currently rebuilding my carbs. The way I found to remove the valve seats, understanding I am not reusing the seats and filters, is to heat the carb up with a heat gun and fine tip around the area of the plug and vakvv. I then use a close fitting aluminum rod and SMALL hammer to drive the valve seat and plug out. They don't look damaged at all. I mainly wanted to change them out to replace the filter element.

    You can use a socket and clamp. No potential damage from heating up the carbs. Should be a thread on here if you search for it.
