318 stalling from idle

Good evening all. I have a 64 Valiant with a "70s 318 bored. 030 over, 273 heads" that I just bought. I put the engine specs in quotes because I haven't confirmed anything yet. My current pressing issue is that once the motor is warmed up, she likes to die from idle if you only give it a bit of throttle, but she's okay if you step on it. This weekend I plan to do a quick tune on the carburetor to get it to a baseline, but I was wondering if anyone had any thoughts or experience with what I'm experiencing that could offer some wisdom. I haven't gotten into the fueling yet, although the fuel filter itself is very clean. My very limited and inexperienced initial thoughts are either the carburetor or the timing is off. Thanks in advance everyone!!
