Rough idle when hot, fine for most other times

yeah, the choke is opening completely when warm. The car came with no choke at all so I found one and put it on. Works well.

That's an interesting point about the fuel overheating...I think that the fuel line from the pump outlet should run down low at fuel pump height and then come around the front of the engine to the carb from down below in a metal pipe. That setup is gone and the previous owner has a rubber gas line running directly up from the fuel pump to a fuel filter. then the line goes over the valve cover and right to carb in a straight line from the fuel pump.

Should I reroute to keep the fuel cooler and see what happens???

thanks for the info so far.
