Hello all! This is my first time on the forum and i have an issue with my 700 that is giving me troubles. Bought sled last year and took up north ,thats when trouble started.Left bank fouling out , took to dealer where they rebuilt flatside carbs to which that didnt fix problem. brought back home and over the year have replaced pistons,rings,oil pump,fuel pump,reeds and had another dealer go through carbs again. sled [email protected] 500degrees on right jug where the left jug is @200. no matter what has been tried i cannot figure it out! please help!
