Well if you are not in a hurry I would soak it with PB Blaster or the equivalent for a day or so then give it another try. It will come loose.
I never have the patience for that, and would have ruined it already. |

Looking at picture wondering why you want the seat out of the carb. I have never had one bad. the needle just fits inside that seat and shuts off or lets fuel in according to float

Drill a small Hole into the Brass Cap on the other Side of the Valve Seat. Be careful and don't go too deep. Put a Wood Screw in the Hole, get it to bite and wiggle the Brass Cap out. The Valve Seat will come out easily when the Plug is removed.
But since those Brass Plugs are not listed in the Parts Cataloge, you better have someone with a Lathe make a new one for you. |

The brass cover plug on top is "staked" in four places with a punch. To get the plug out, use a small (~1/8 or 3/32") drill to drill a SHALLOW hole just deep enough to remove the staking/deformation at each of the four locations, but not all the way through the plug. It will come out easily, and the seat can be removed. You can re-use this plug by staking it with a punch in different locations when you re-install it. Just don't drill all the way through it.
Also there is a strainer screen in there that, especially in the Left-Rear carb, will be corroded because it's a low point and that's where water drops in first if there is any in the fuel. If you don't use a replacement screen, scrub the old one or soak it in an oxalic acid solution (the screen not the carb body) and clean it up. It's stainless, which in the presence of water galvanically reacts with the carb body metal and clogs up, so it should be cleaned thoroughly. |
