So my old weedeater xt 300 has finally decided to act up.Ive cleaned the filter which was new looking(fuel).Adjusted the carb ,cleaned with carb cleaner.It will only run with mid choke .So do I rebuild the carb,buy a new carb,or buy a new weed wacker?Its given me about 15 years of faithful service with not even a plug change in that time.Put a new plug in it this year just because.
