I have looked at both of your threads. Let me start by asking is this your personal fourwheeler and how old are you. Would like to try and help out but just want to know the basics. I think we all here on the forum may need a little more info. With this particular problem it seems like your choke may need some adjustment. Also how old is your fourwheeler..
