There are only 4 screws plus the fuel line holding that carb together. Pull the top off & see what you have. Its probably got a bunch of white stuff or water in the fuel bowl.
If it is not too bad clean it all up & put a kit in it. It might be like Panel Fan says, it might be a 235 carb & too lean for a 261. Although a .072 jet is too big for either one. Otherwise get another carb.
Those model B carbs are not all that bad. There are thousands still running around out there every day & at car shows.

They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
