Slant Six Carb Issues

Hey guys. I’ve been having some carb issues lately and I’d like to see what you guys make of it. I got a Slant six with a Holley 1945 1bbl carb. Recently, it died on the side of the road, just pouring gas down the manifold. Had to readjust the floats on the side of the road and get it home. It ran great then. Now, it seems to be running rich again. In order to get it to idle relatively well, I have to turn the idle mixture screw all the way in, but it still doesn’t run or drive great. What do you guys make of this? I want to get it running good again so I can drive it to my uncles house and work on the body some.

Thanks in advance.
