440 wont start when hot.

Hello, we started out as a fuel problem and now we mixed in ignition.

What carb?
I've seen this many times before. Hot engine, shut it off and quickly remove the top off the air cleaner. Do you see "fog" coming off the choke tower? If you do then the bowls are boiling off or draining out the idle circuit holes into the manifold.

Need carb info to elaborate more.
