It pretty much is. You origanally asked about a high idle, and we reccomended you not change the idle as it would probably create other issues and you needed to fix what was causing the fast idle. 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.

Thanks ferm I know you are right about that I have to get a drum and put my motor in it to adjust the idle I will be doing that as soon as I get the drum,that's where my son comes in,getting the drum , I never had that problem before where I almost stalled and started to smoke heavy all of a sudden, never seen that before, also the adjustment was very minimal so if I had to I could get it back to where it was before I turned the screw

Most 2 strokes adjust the idle speed via the timing. It only takes 1 or 2 degrees of timing change to REALLY screw up how the engine runs. Fuel needs compression to ignite, and if it ignites even a degree or 2 to late, it may not be under enough compression to fully combust which causes ALL kinds of problems.
