Ethridge, TN | Without being there to hear it, I was just wondering if what he might be hearing wasn't an air leak. The harder you run it, the louder it "should' be. I've seen 2 different aftercoolers on the combines crack on the bent corners of the cooler. Could very well still be a fuel problem, but usually lots of black smoke equates to unburnt fuel. So if the air system checks out, then it might take a computer to figure it out. Could be dumping fuel late, or if the injector tips have gotten bad, it might be it's just dumping fuel, without atomizing it properly. George's idea of an electrical connection to an injector could also be a possibility. Air system is exposed enough, to just eliminate that possibility first, before you start opening things up. | |
