I have a 1992 dr250. It was leaking gas out the carb and running rough. I pulled the carb and cleaned everything. Put it back together and it ran like a new bike all day. No issues at all. I parked and went to ride it the next day and it won't start. I have kicked it many times and tried to push start. It will not even try to start. Now there is gas pouring out the bottom of the carb. I pulled it again and floats are working. I have spark. What could be the issue as this is driving me crazy. Ran perfect one day and now will not start. Any help would be appreciated.
