You could still have a bad coil or ignition condenser, or a starter that drags when hot.

That said, flooding issues are very common after a hot shut down/restart in summer weather.

Modern gasoline is not designed to work well in carbureted systems. It's too volatile. It's not a problem in cool weather, but in hot weather and under some driving conditions, it can cause issues, especially if there is anything to aggravate the situation, like a leaky carburetor, air leaks in the fuel system, weak fuel pump, cooling system issues, sticking manifold heat valve, etc.

Even a slipping fan belt could cause problems, as could bugs in the radiator core, or anything else that reduced the efficiency of the cooling system.


A fuel line or added filter or fuel pump that is too near the exhaust or other source of heat can cause problems, usually in hotter weather.
