I fixed that problem I had with my bike pissing gas out of the over flow tube coming out of the carburator. Every time I would try to kick it, the bike would leak gas. I pulled out the carb. did some simple surgury. Come to find out there was a little piece of debris in the float valve housing. So the float valve was not seating properly. wooooooooooohoooooooooooooo!!!!!!!!!
