timing?????

I have a 65 GMC with 305 v6. It has holley 550, Electronic ingnition, valves adjusted. Great truck.

Here is my questions. Sometimes it runs perfect, other times it sputters up through carburetor. Is it timing? Jetting?

Getting ready to turn it over to my 17yr old for his daily driver and want it running perfectly.

Thanks for your input
