Sure. When your rich the motor gets more oil and fuel which lubes it more. If it's RICH it will overheat and burn up because of lack of lubrication.
I run 50:1 because of my setup but yes you should run 32:1 and anything richer than that is better. I believe two strokes run most effiecently at 13:1 or something but thats not economic and oil will be a major $$$ setback. Just run 32:1 or richer if possible. I know people that run around 25:1 and the motors last longer but they foul plugs slightly easier.
