I have a 68 coup that I am trying to get running again. It sat in a barn
for several years (about 5). The only way I have been able to get it
running is to pour a little gas (or even spray starter fluid) in the carb.
The carb I belive is a carter carb with 4 barrels. I've tuned the car up
(changed all the plugs/wires/distributer points and condenser).

When sitting in the car (with the motor off) pressing on the gas peddel I
can hear what sounds like a small pop comeing from the carb. I am assuming
it's trying to relase gas into the carberator.

When the engine is running and I step on the gas the acts as though it
wants to die untill I let off the gas. Slow acceleration is fine.

The choke knob inside the car seems to do nothing, but that maybe unrelated.

Thanks for any input you may have.

The diaphragm in the accelerater pump is shot. It dry-rotted from
sitting. Rebuild your carb.

Try checking the accelerator pump? With the engine OFF, look in the carb at
the same time you work the throttle back and forth, it should shoot a stream
of gas into the carb.

I had the exact symptoms as you on my 68 302 and it turned out to be the
accelerator
pump, I'm not sure what it is on a Carter but mine was a plunger like pump
and bacause
it had been sitting with no fuel in the carb for a while the rubber plunger
shrunk, I
stuck another on (about 3 bucks) and all ok. I think the other type of
accelerator pump
is a diaphram system.

Hope this helps
