Adam,

You have discovered one of the pitfalls of this carburetor. I can't give you a blow by blow fix for this problem, but here is what I have read.

I think the fuel bowl is alright..it is the air horn that warps. A dead flat fixture plate is made with a bolt pattern to match the air horn.

The air horn is screwed to this plate and the shebang is put in your wife's oven to bake at 350 degrees for a hour or so.

This heating process will normalize the casting and relieve any stresses in it...it will be flat again. Turn the oven off and leave the "carb pie" to cool on its own.

I might be mistaken, but I think CARBKING outlined a procedure something like this in one of his many posts.

Carburetors are a hot subject here...lots of war stories will be forthcoming I am sure!
