Fuel Bowl empties when stops!

Hey Trail Beast,
First off that is not a 225 c.u. 6 cylinder that you fired up.
This is a post on things to do and try on a 6 cylinder van or car. Have you ever looked at where Chrysler routed the fuel line or how they mounted the carburetor directly on (3 inches) above and bolted to the exhaust manifold collector and heat riser.
Our problem is the shitty gasoline. To much corn in it now. This is NOT a drain back problem, its a boil over and flooding problem. My God I can drive mine tell it gets good and hot, which is normal operating temperature, shut it off, let it sit for a bit, open the hood, look at my carburetor and watch it boil over.
