Default ofna picco .12

I have a picco .12 motor that has about 2 gallons of fuel ran through it and i took the motor apart to give it a good cleaning and i noticed the top of the piston is really black. Is that normal? if not what might cause this? i run o'donnell 20% fuel and the motor runs great!

The black color on top of the piston is normal, meaning your tuning of the motor is good, If I were you I wouldn't worry about it.
