Ok I'll explain the best I can, the car will run for about 10 to 15 minutes on the highway, when I get off the highway and get on the back roads and hit any traffic it will start to load up and if I stop, I have to keep my foot on the accelerator or it will stall, then when I take or back off the pedal it will cut off(stall). A Carter AFB(clone)9635SA is a version of the original Carter AFB's but made by Federal Mogul not Carter as Fed Mog bought Carter. The Carburetor wasn't thrown together, I tore it down cleaned it the threw it together. I also own A Chilton Manual,67 Pontiac Service Manual, I use the forum's for input and what maybe the cause, the people here do help if they can, because this problem had me stumped. Now I found a vacuum leak today at the manifold vac port for the PCV, the fitting wasn't the correct size and was leaking I replaced the fitting and while at it I replaced all the Vacuum lines,after that I ran it then the plugs fouled out, what does it mean to rich, my timing is set to factory spec's 6deg BTDC.
