Dieing Out

[JeffersonC]

Alright, 1977 Monte Carlo. engine is in alright shape. 2 barrel carb. cleaned carb, filter, plugs, wires, etc.

Now, when in nutural or park, and you rev the car, its fine, no bog no stall. But when I am driving, and I punch the gas it sometimes dies out. Its only when say I try to spin the tires, so basically take off from a slow, or dead stop.

What do you all think ?

Thanks.

..... i kinda know how carbs work....

is it running rich?.... does this happen all the time, or only after it warmed up, or only when it's "cold".... could the choke sticking do that?

i'd just imagine either it's leaning out to much or it's flooding the engine.

Yes I am thinking carbs aswell. I can't tell if its getting too rich, or lean, when it dies out. And it is only when driving the car, like pulling load. In nutural and park it revs totally fine, from like 1500 to the floor, no dieing.

Hot and cold, does the same.

Carb float could be stuck, if its the stock carb you have no float adjustment except for cranking it and "gently" tapping the float bowl with a screwdriver. Another thing could be fuel pump related. Could be an internal problem with the fuel pump, since it is a mechanical model that isn't allowing it to do its job and boost fuel pressure properly when under a load.
