When my 40 Commander sits for an hour or so the bowl in the carb goes empty. There is no sign of gas leaking but it will not start till I crank long anough to fill the bowl again. Once running it is fine. It's a Carter single barrel.

Anyone have any ideas ?

Its been literally over a decade since I even looked at this engine,
but look at it to see if the fuel could be leaking back down to the
fuel pump, its possible that the fuel pump is not holding fuel in the
line up to the carb. Extreme heat can also cause the fuel to evap.
Sorry thats not much help, I am trying the picture the engine. We had
a 1940 Hearse, and a 1939 Custom Coupe, a long time ago.

Maybe an electric fuel pump would solve the problem. Champ:)

BTW, If you decide to go with the electric fuel pump a fual pressure regulator would be a good idea! Champ:)

Does the engine act as if it is flooded when it does finally start? If so, the fuel could be leaking from the float bowl down into the intake manifold, if there is a "blown" gasket or a check ball that has a piece of trash under it. Just food for thought. OBTW, does it have a fuel filter? Might be a good idea to check it. Make sure it's sealed ok.
