I have a 1974 Mustang II with the 2.8 v6. This car was given to me about a year ago by a friend. It is pretty rough on the outside but was told it had a rebuilt engine with about 1000 miles on it. It had been sitting awhile before it was given to me but was kept inside. I havent spent much time doing anything with it yet but the first problem I want to tackle is this issue with the engine. First of all it is very difficult to start. I usually have to pump the accelerator for quite awhile before it will start. Once running the engine sounds great, but when I accelerate from a stop it will cut out and die or almost die. Usually if I let off the gas and feather it a little bit I can keep it running. I am not a mechanic but can do some engine work if I have some direction. Just trying to get an idea of where I should start looking to solve this problem. One thing I have done is put a new diaphragm in the accelerator pump. Thanks for the help
