Hello, It seems my carburetor isn't functioning the way it should. 72 350 GS. When idling at a light, it starts running rough and conks out. I am not at all mechanical, so I will just have a mechanic do it, but since parts are hard to come by and take time to ship, I figure I'd just order it and bring to him. I am open to any suggestions. I wonder if I am best buying a new one, refurbished one or have mine rebuilt. My car is completely stock. While I am at it, I need an original AM radio or AM/FM stereo. I bought a beautiful looking AM off EBAY, but turns out that it did not work Thanks for your help. Jim.
