The Stovebolt Site Forums The Shop Area Engine Shop carb issue, runs rough for while, then stalls, then gas leaks out the backs

A couple of thoughts:

First, the leakage AFTER the engine dies:

Now, as to why the engine dies:

Since there is sufficient fuel in the carb to leak out after the engine dies; there is sufficient fuel in the carb to run the engine. However, coils when they fail, tend to do so as they heat. I would check the ignition system before spending much time on the carburetor.
