It's pretty obvious this is a fuel delivery problem. Depending on the carb, it has several fuel circuits, one of which is the accelerator pump. But that's not your problem. What you are describing is the tell tale signs of poor fuel delivery. Hence why I said check fuel pressure. It will cost ya 10 bucks for the guage and 5 bucks for enough fuel line to run it out behind the hood so you can watch it while driving. I'd be damned if I started wasting time ------- with other ---- and throwing parts at it before performing simple standard diagnostics. But yeah start changing more ---- and see how much money you can spend while seeing how many variables you can bring into play. And if it's the OEM carb junk that and get something better anyways AFTER fixing the problem at hand. 427 T-bird loved a nice vacuum secondary carter.

i know they suck, but i just lost my job, can't afford a new carb.

why would fuel pressure have anything to do with it? if i'm in park and rev it to 5k rpms it's fine. i can hold it there forever and it's fine, but if i'm driving and i gas it, it falls on it's face.
again i'd love to throw a different carb on this car, but i don't have the money.

so lets say the fuel delivery is bad, how would i find out where the problem is?

I had the same problem on my '82 mustang I went and bought another carb, tune-up, re-set timing, re-did all the primary power cables. I end up replacing the fuel pump and solved the problem.
I know you replace the fuel pump but I had to replace the fuel pump three times in a month before I found a good pump. Your fuel is under warrenty right?

I tried to be diligent and ready every post to be sure I didn't duplicate anything, but lost interest and figured I'd better just post.

Fuel starvation could be the pump, the filter, a clogged line, etc. But starvation can also come from the float level being set too low.

If this starvation deal started only with the new parts, then something there might be at fault.

Also, on the old fords, the coil wires were connected with push on fittings, which sometimes get loose over the ages. I had one that was so loose that under acceleration, the connection would open just from the wire moving back, and then reconnct as the engine died and the wire would move forward. Behaved just like starvation.

Hope that helps,

Insufficient fuel pressure is either because of a bad pump, or a restriction between the fuel tank and the carburetor where pressure is measured. Say the car ran fine and then I take a fuel line off and put a .050" restrictor in it. The car will still crank and run at idle, as there isn't enough flow gong through the restriction to cause much of a loss in pressure. But if you tried to drive the car, and then fuel supply needed increases 10 fold, that restriction is gonna cause pressure to go to zero and the engine won't run.

Like I said, check fuel pressure. This will tell you if there's a fuel supply problem. Others have said different things that could be the problem. So try rewiring the engine, replacing the carburetor, replace the transmission, adjust and ---- with everything, eat OC, and when that doesn't get it going right, check fuel pressure. If fuel pressure drops you at least have narrowed it down to the fuel system.

lol
i'm gonna get a new engine for it...
j/k
i'm gonna get a pressure gauge today after i put a new fuel pump on my car (65 nova)

also my wife reminded me that we put the new fuel pump on cause it was doing this.

so it was doing this before the new pump went on.
when it started doing this i took out the fuel filter and there was major ---- in there so decided to replace the filter. when i got to the store i said ---- it lets replace the whole pump.

file your points

Wank.a.lot

points are fine, thank you.

sexyblackcrx

fix the kink in the fuel line.

reason is doesn't bog while not in gear is the same reason you can't build much boost in nuetral, no load on the motor.

Have you check the fuel filter AND be damn ****** fovking sure to replace the rubber fuel line at same time!

That rubber fuel line is right next to the dizzy.........got marshmallows?
