My '65 Mustang's Engine cuts out when I attempt a quick acceleration. This problem came out of no where...If I feather the gas, no big, and it does fine on the freeway once it's up to speed...But it's a bitch to even start it up sometimes...my buddy and I think the carb's to blame, anyone else have any ideas?
Much Appreciated,
Chrystie

Unless you're not running a fuel filter, and you've been feeding it dirty cheap fuel, it's just as likely to be an ignition problem.

It sounds like a bad accelerator pump, at first blush. With the engine off, and air cleaner off, look straight down into the carb (open the choke manually if you need to). Open and close the throttle. You should see a healthy stream of liquid gasoline squirt into the carb, just below the choke plates. Your post doesn't even hint at what engine or carb you've got, but it's generally not a big job to replace.

If it's a Holley, red65 is right. Did it backfire thru the carb before this started??

also check for vacuum leaks. See if any vacuum hoses popped off anywhere.
