Repair & Maintenance Honda Rancher 350 cutting out & surging. September 8, 2015 Just put a new carburetor on it today because it wasn’t running right. Now when I go downhill it wants to run fast and going uphill it cuts out. (I bought it used). It is also smoking some, blue and white smoke. Any clue what could be wrong????
