Stalling when accelerating

Been a ford truck buff all my life and never ran into this. 1972 ford truck stalls when I accelerate on the gas petal. 2nd rebuilt carb on it. Could this be the vacuum advance? Can anyone help me out on this ? Thanks...

Auto or manual trans? Check for vacuum leaks? Check for a clogged fuel filter?

Had a similar problem on my 72 360 just last week. Thought it was the carb. I had just recently rebuilt carb, new points, condenser, cap, and button. Was running great. Went out to drive it and I couldn't keep it running over an idle. Rev it up and it would spit and sputter and backfire. Finally narrowed it down to the condenser that i had just replace not a month ago. Cheap part to try. Just my .02

Condensers have been the number one culprit of all running problems lately. I tell everybody to get a pertronix kit.

2X pertronix kit part # 1208 if memory serves me correctly. I'm old so I don't put too much stock in it

If you don't go Pertronix go to your local Ford dealer. Ford V8 (single point dizzy) condensers are part number C9AZ12300A (DC-13A). Still available.

On his other thread he mentioned Holley 4V. And after installing it is when the problem started. I asked quite a few questions about it on that thread Bobby.

Worked on the 1972 today, fires right up when cold, sounds great until the idle comes down (hot air choke on it)then is either dies , like shutting the key off or rough idle until it quits. Air fuel screws are approx. 1 3/4 turns out. Can keep it running long enough when warm to even check the timing. This one is really driving me nutts. Any one have any ideas? thanks again for the help guys... (This has a 2 bbl carb on it)

Yep. Change the condenser. There was someone else on here a while back with the same symptoms. Must be a certain engine/dizzy/condenser temp that made his and yours go wacky. This is only one of the symptoms. As Garret said, condensers have been the #1 culprit as of the past couple of years. Whether it be new, used, or new in a replacement Dizzy.
