Some good information here. Black plugs indicate too much fuel, (as a start). The fuel pump on your 8BA should be running at about 4 to 5 pounds pressure. Nothing more! The second black plug issue, (in my book), is spark. Are your points set right? If the gap is too small, the spark will be less, thus failing to provide enough spark to ignite all the fuel. Third is basic carb jetting. If you don't know how to properly set the jet, find someone that does. It's not difficult, to set, but can easily be damaged. Sending your carb off to be tuned is good. However, in my opinion, it cannot truly be properly tuned if it isn't on the engine
