I have a 1957 2 stroke 18 hrs Johnson outboard motor. I added sta-bil to the fuel and drove it around for several hours last sunday. Somebody told me that's all I have to do. Somebody else told me I don't have to do anything because it's a 2 stroke. People at my job just told me I have to drain the oil out of my lower unit. I am having trouble finding information on old, small, 2 stroke motors. Does anyone have a motor like this or maybe has had one and knows what to do?
