My carburetor keeps dumping gas

I think I will try a different carburetor. I purchased a new holly carburetor a year ago. I think I will try that. I will just need to use a adapter plate. It’s 4.25” to 5” carburetor.

I see, so that's like an early AFB, right? That could be a good choice if it's in good shape. They were fine carburetors. A little on the lean side, but probably not as bad as what you have now. Keep us posted.
