By lowering the idle you created problems. Most likely you retarded the timing to lower the idle, which is going to cause a poor burn, and fouling of the plugs. 1st you need to put the engine in the water or a tank so as to have water at the height it would be with it in the water(2 strokes MUST have CORRECT backpressure BEFORE you make ANY adjustments to the idle speed as backpressure controls how the engine runs), then you can adjust idle speed if needed. You could just have old gas in the carb bowls that isn't burning correctly, and need to put fresh gas in it, but you never make idle speed adjustment to a carbed 2 stroke unless it is under the same conditions it will be run under.
