stalling

Here is a new one for you guys.

I have a 318. Stock with an Eddy manifold and a 600. Also elctronic ignition. In the last 3 months and only when it is hot outside and the car has run for awhile, will start to get sluggish and stall. This only happens at a light or when the idle is low. Have not tried, because it happens when i am not ready at all, but beleive I could hit the pedal and everything would be fine.

I was thinking that maybe the fuel line is getting to hot from the header. The guy that installed my manifold and carb used a fuel line that has cloth braided over the top. I honestly do not know what kind of tubing it is.

Also, when it stalls and I try to fire it up, it smells like it is flooded. It sits for awhile and fires right up.

Thoughts?
