Black Smoke on Startup
Ever since I got my 147 it smoked a little on startup. Only a few seconds then it cleared up. It used to be blue/gray, but recently it has been black. We changed the spark plug about a month ago, and it was smoking blue after that, but now it has been starting to smoke black again. The plug was fouled with white carbon or something on it. Is this anything to worry about? And is there anything I can do about it without rebuilding the motor?
