Have been have advised to go to a Carter as they also have had over feeding with Stromberg carburetors of this era.
I can't say I've ever experienced that, much less heard that it was an issue. Those Strombergs are really fine caburetors; I'm not aware of any particular weaknesses much less chronic ones. If you remain stumped you might call Daytona Parts or the Carb. Doctor and ask them.

IMHO you should stick with the OEM Stromberg and if you have problems, then send it to Daytona as Owen suggested.
I have that Stromberg carb on my 1941 160 Convertible Sedan and when I restored the car about 10 years ago I sent the carb to Daytona and it came back looking like a piece of jewelry. About a year later I was getting a massive fuel feed and it took me a while to figure it out - actually my brother figured it out. We had the carb apart and he noticed that the brass float seemed a little heavy. So he put a heat gun to it and saw some vapor coming off the surface. Seems the float may have been in the dip tank a little to long and got a little porous in a small spot and was now 1/4 filled with gasoline. With some modest heat we were able to drain the float and dry it our. Rather than wait and hunt for a new float bowl we just "tinned" it with a lick of solder. Has been fine ever since. How airtight is your float?

I don't know what kind of fuel pump is usedon that car if any but need to check fuel pump pressure. If excessive pressure from the pump then that can cause flooding.
WHEN does the flooding occur??? If only when hot thenit is due to the fuel vapourizing aand that is a common problem with modern day fuels and not withthe carb itself. Also note that the float can be tested for leakage simply by shaking it and listen for fuel sloshing inside of it.
