I have a 2004 CBF50F dirtbike that has been sitting for a year. It starts fine with full choke but without choke engine dies. I have replaced the gas and added a small amount of carb cleaner fuel treatment still no luck. I have also turned the throttle set screw to make it idle a little higher that seems to help but still have to run some choke or it dies. Any help would be appreciated my 6 year old is ready to ride and is asking everyday when its going to be ready.

 

a year is a enough time for gas to start turning into syrup if there is no room to fume. remove the carb and clean it, replace any parts that are victim to the neglect.
