Question
I am the owner of a 68 ford mustang that I have had for over 15 years. The car has always had one problem. it will stall from time to time when you begin to move it from a stopped position. This has done it some days worse then others. I have had numerous carburators put into it, have had the vacuum lines all checked and had all the fuel pieces replaced numerous times. the points and plugs are all good. I have spoken to two other owners of the same car who complained about the same issues with no answers. I cannot believe there is no answer for this. Just picture sitting at a light, the light turns green and if you hit the gas petal too quick it will stall, not hard enough it stalls, is there anyone who has had the same problem or any suggestions, any help would be greatly appreciated please email to boston18@gmail.com. thank you for your time.

Answer
The first thing you do is find a mustang or ford car club and join it.  They should know about the problem and be able to help you.
What else could it be????  It could be a wire that is thrown rearward and hits something that shorts it out for a moment. Just give it good look for something like that.
A small vacuum leak usually causes an engine to stall upon decel.  I assume the spray pump is working.  That would do it.
Also, I was fooled years ago by assuming a new part was good.  It was not and it took an old timer to tell me what was wrong.  Make damn sure all those new parts you put on are not fooling you.  
Try it while in neutral and see if you can make it stall that way.  If you can, it will be easier to find the prob.  Check out the spark advance mechanism.  Things in there move when you hit the acc. pedal.  Maybe a little short when it retards for a moment.  
That's about all I can think of.
Good luck.
