I have what I believe is a 92 motor. It is a 120 Johnson two stroke, VRO. I disconnected the VRO because of all the trouble I heard they can cause when they are older. I ran it for close to a year with no problems. The motor never sat for more than two weeks without being ran. Recently I have been fouling my plugs, and felt a loss of power while running. I think one of the cylinders was missing, and then fired back up. I changed my fuel water separator because it was clogged and cleaned the fuel filter under the cowling. The motor still sputters when I start it, and doesn't always start on the first try. I was told I should decarb the engine, but I don't know how effective that would be. I was thinking about rebuilding the carbs and hopefully solving the problem.
