Condition #5 -- The Engine Is Hard to Start When Hot.
Some hot starting techniques:
If the carburetor is flooding, the hot-start technique is to SLOWLY put your foot to the floor (so the accelerator pump in the carby doesn't flood it with more fuel - it only works when you floor the throttle quickly), and then hold the throttle open (no pumping) while you crank it - it should catch easily.
Some possible causes of hot starting problems:
The air filter clogged.
Fuel may not not reaching the fuel pump or carburetor.
The battery ground connection may be corroded.
The starter motor or solenoid may be worn.
The automatic choke may be defective or incorrectly adjusted.
Your system may be suffering from vapor lock -
Cause: The engine overheats, causing the fuel line, fuel pump and carburetor to heat up. This results in excess vaporization of fuel in the carburetor and/or actual vapor lock in the fuel line or fuel pump.
Cure:
Wrap the fuel lines on both sides of the pump with aluminum foil.
Note: This is a precaution if your car is prone to vapor lock. It won't help much once the problem has already occurred.
Pour a little water over the fuel pump to cool and re-condense the fuel, being careful not to splash the distributor. If no water is readily available, hopefully there is some in the windshield washer bottle. It doesn't take much.
Hold the throttle open just a bit with the accelerator pedal while you crank. Don't move the throttle at all while cranking, or the accelerator pump with flood the carburetor. The reason for cracking the throttle open it to avoid using the idle jet alone, as this runs the car richer than the main jet, and a rich-hot mixture makes the car flood easily.
When the engine catches, hold the throttle still until it clears the excess fuel (revs up smoothly).
MORE THAN LIKELY<, IT IS VAPOR LOCK> All of those things happen with cold motors also
