My Octane will not stay running. I have returned needles to factory (LS 1 7/12 out and HS 1 full turn out), checked fuel mixture (25:1), Checked spark (I have spark and ignition system is at full charge with new 1600 Plazma batteries), No drive train issues. I cleaned and rebuilt the carb, same thing. I have been using Trufuel and emptying the tanks after every use, I pull the cord to make sure all the gas is out of the carb after each use although I have not done this with EVERY use. I am stumped. Maybe I just need a new carb. Any suggestions will be great
