Won't stay running

[terabytemc]

I got my Model A to start after sitting for 1 year, but it only runs for 30 seconds and dies. I have fuel getting to the carburetor because it comes out of the airflow when choking (after repeated restarts). I also see a gas stain that has formed on the engine at the manifold line, probably because I flooded it trying to restart it so many times. Any suggestions?
