Can anyone please help. Been working on this issue for 6 months. Have 1975 manual 350 with Edelbrock 1406 electric choke. The engine starts fine but when you drive or rev the engine the car will idle down to a stall. You turn the key and it starts right up. (not flooded) I've changed the plugs, wires, fuel pump, standard coil, and sent the carb back to Edelbrock and was rebuilt.
Does anyone know what could be causing this? Please Help!!! I completely out of ideas.

Thanks

Sounds like its not getting enough gas ,I would look at the float level and the accelerator pump .

what is your idle set at? Mine does this after running down the highway at 3500 rpm then getting off the highway and stopping at a light. My idle is set between 750 to 700 when started but when it stalIs it tries to idle at 500 rpm. I think I set it before the choke high idle was fully cleared so I will reset it again when its fully warmed up. You may have a similar issue. You can also try making your idle screws a little richer

Also check all your vacuum lines, if any of them are loose, they may create a leak when they get hot. You can trim the ends or put clamps on them.
