I'm guessing this is my reason for the rich condition. Went thru the carb and all is clean. Do you squeeze out both the pre and the main filter or just the pre or what? Thanks!
You also have to keep in mind that when you run on grass you will most likely have to richen the motor due to the grass being harder to run on, then when you get ont he track like you said the motor will be rich, always try to tune on either the track or some were that has the same type of surface.
