273 Won't Run When Warm - Carb Issue?

Hey All,

Like the title says my '66 273 2 bbl dies when it warms up and once it's warm it won't want to start anymore. I believe it's an issue with my carb. To give a little background it's got a fresh battery, fuel filter, new mopar organge box conversion w/ fresh plug wires, dissy, a new coil and ballast. Fuel delivery to the carb appears to be good. Timing is around 5-7 BTDC.

It ran fine for months with the new ignition and only on a hot day did it start having any issues. Now it's like clockwork, as soon as it warms up it will die and won't want to idle again until it cools off. I've checked too and it's not overheating, it has issues just before normal operating temp - according to my factory gauge.

Any tips or should I just go ahead and rebuild the carb like I planned?

Thanks.
