Autolite 4300 4V carburetor

I have a 72 N code 429 that runs great under normal driving. My problem is, any time I floor it, it will then flood when I come to a stop and die. I have to restart it as a flooded condition and two foot it home. Has anyone else had this problem? 
Thanks in advance,

Re: Autolite 4300 4V carburetor

Not sure what is happening, but the first thing that comes to mind is the choke. The initial pump of the gas pedal on cold starts is to set the choke to full rich and high idle for the cold engine to start and run. the high idle is supposed to come off when you kick the throttle down. Your choke, and/or high idle, may be being set, even though the engine is warm and the choke should not come on, when you floor the gas. That may explain the rich condition you experience after going full throttle on a warm engine. Have you rebuilt the carb? it sounds like a good cleaning and replacement of worn parts is in order.
