They say that there are no stupid questions. My Kaiser hasn't been started in several years (old story) and today I finally got it running! Before it's period of rest, I put Magic Mystery Oil (or whatever it's called) in all cylinders (plug openings) & in the oil. Almost everything is new. When started, it ran smoothly BUT billows of gray smoke continuously were emitted from the exhaust...I mean billows. To cloud up the area and kept on while running for about 5 minutes! My question for you motor types, is it the MMoil, a stuck ring, will it burn off, would an oil change solve it? I'd like to know the answer before smoking up the neighborhood again! Any educated advice would be appreciated. Thanks, Karl
