had my bike running mint and rode it for like 3 hours and I went to ride it after about 2 or 3 weeks of sitting due to bad weather and it starts fine and idles fine but as soon as I give it gas it dies. If I give it choke and let it idle and go WOT with choke on it will rev up for a little bit and die. Any suggestions? Gotta be a carb problem. Too lean I'm guessing? Maybe someone played with my fuel screw.
