Truck only starts when temperature is warm

My Ford 302 (1974) won't start in the morning or early afternoon. I am getting fuel and plenty of spark and can smell fuel so assume it may be flooding.

however, in the afternoon, I will go out and the truck will start right away and runs great.

I've replaced the fuel filter, put in a carb kit.

The outside temperature is warm - 50 degrees in the morning and 75 in the afternoon.
