I know on a 4-stroke you can look at the plug after it has run a little and look for the color. Black means rich, medium brown means just right, and anything lighter means lean. It should be similar for a 2-stroke. I would think it would be more critical on a 2-stroke too. Lean for a 4-stroke usually means higher operating temperatures, whereas lean on 2-stroke could cause the motor to seize. Check with a professional before you run it--I would.

The same colors apply to 2-strokes, you are looking for a nice shade of light brown. You have to check the plug by pulling it and reading it in the three stages of the throttle. Idle, transition and wide open. For transition and wide open, you must hit the kill switch at that throttle position and read the plug immeadiatly. Another thing to note is that 2-strokes are very sensitive to big temperture changes. Just right at 70 degrees could very easly burn it down when the temps fall bellow freezing. Hope this helps I'm by know means an expert! One thing I can tell you is that jetting makes a big differance ! even on a stock machine.
