71 C10 shutting off

[Darreola562]

Hello forum!!!!

I currently have a sbc 350 carbureted engine that seems to die every time I put it in gear. I bypass this by adding a little acceleration to the truck from keeping from shutting off but once it gets going it goes. It seems when you put it on drive or reverse, the rpms drop very low causing it to shut off. When I start it it does struggle a bit to stay on for the first maybe 20 seconds but that maybe because it’s carburated IDK it’s my first carb engine in a long time.

Let me know your thought it is an automatic truck.
