Fuel Line Mod Done - Still Having Hot Restart Issues

This is almost certainly not fuel starvation, but flooding due to percolation

That does make a lot of sense. One time last week, I had just restarted it after it sitting for maybe 10 minutes, and of course it was hard to restart, idled erratically after finally starting. I drove 2 blocks, and as I sat at the stop sign, it died. When I went to crank it, damn if I didn't flood the thing somehow. I pushed it into an adjacent empty lot, and after me messing with it for maybe 20 minutes (time to cool off), it started right up like nothing ever happened.

I already got a rebuild kit from Daytona Parts. Their resto service is just a bit out of my price range right now. I didn't get a new float, but I'll see if I can find one. If memory serves me correctly, in asking the guy at Daytona about if it came with a float, I think he said that the 1920 comes OE with a foam float, but what we want to use is a brass replacement, right?

I'll also be checking the carb base gasket, and making that heat shield.
