If you have trouble don’t hesitate to message me I’ve built an repaired hundreds of them just once your done pay close attention to how they idle, the solenoid valves are notorious for going bad on them and most times still to this day most dealers won’t tell you this but it is part of the emissions fuel system so it carries an extended warranty. I’ve warrantied saws from as far back as 2014 already an they still pay the claims!
