750 Edelbrock carb

Wanted to run this by you guys, tried changing the throttle shot to the top hole more gas no change went to the lean hole no change.
The weather here changed it got really warm today in the low 80’s took the car out for a spin after it got up to 190 I punched it on the freeway and it worked it hit the passing gear didn’t stumble or sputter, the water temp usually never gets over 180, why when it’s hotter out and the water temp got to 190 would it run better.
Should I put a hotter thermostat in the car
