My step-Dad gave me his old ‘85 ATC250ES Big Red year before last. I had the carb cleaned and replaced the lines going to/from it because it had sat for several years. I had to put a new tank on it as well. When I try to run it, fuel will drain out of the carb vent/drain line if it’s just idling. It didn’t do this at first and then only occasionally would do it. Now it does it every time. Any suggestions?
Thanks!
