My daughter has a CRF80 and the carb would continually leak gas, I tried to adjust the float several times, cleaning the carb and nothing helped. I finally replaced the entire carburetor. The new carb ran great, perfect idle. The only issue I have is that when you are riding it and get the motor to top end in any gear it starts to sputter very badly. I am not sure what causes this and how to fix it. I do not want to mess with the idler of fuel mixture because other that this problem its running great.
This is a great forum, thanks for the help!!!
