Can some one give me a few pointer on my carb. They bike has been sitting this winter,but it was started two times a month and left run for 15 to 20 minutes. Today after I got it out it will not idle and it appears that it is flooding it;s self.I have to keep it rev up to keep it running,then after about a minute I see gas dripping from the bottom of the outside          bowl area. When I pull the choke out the bike stalls. If I let the rpm slow down the bike stalls. Any suggestions will be a great help.
