Hey why dont you try to turn the gas on to fill the carb.For a few seconds.Then shut if off and try to start it with the choke on.If it starts and runs turn the gas back on.See if it floods out.But if it starts dont run it very long with out the gas on.Do this and let me know whats happens.I dont want you to do to many things at one time or we wont figure it out.Let me know asap after you do this and if its runs.
