Motor is hard to start after warm up

Just for giggles, next time you have some time, before you get in and try to start it up, see how much gas is in the fuel bowls. Take the top off and look inside.
My old AVS leaks at the throttle plates and drains some. The first time I get in it after a day or 2 or a week or 3, I need to turn it over for about 10 - 15 seconds and then pump it a few times to get gas running through the carbs passage ways.

Let it be known that I have not really had the chance to finish tuning the carb or drive it around. It has no plates. But I did do some work to the car and does , everyonce in a while need to be moved around. You describe my car in your discription of your car.

Have you had a chance to close the choke slightly after it sits for a bit?
