"I have a 1986 4-108, 2700 hours. Engine has been running fine with no smoke, then the injection pump started leaking, so I had it rebuilt, then reinstalled with timing marks aligned. Heavy black smoke started at wide open throttle, full load. Had the injectors rebuilt, new lift pump, new exhaust elbow, muffler, hose, etc. Pump rebuilder has suggested advancing timing slightly. Any suggestions? I am baffled as it was running perfectly before all the fuel system repairs."
