Ariens zoom 1640 zero turn mower. Mower will creep rearwards at idle and the steering leavers are not align when mowing straight, the left is about 4" forward of the right leaver. Can this be corrected by an adustment, if so please tell me how.Thanks for your time and troubles. Ron Thanks for the carb info, I did resoak the carb and this time it worked out, it has no surge at all, Thanks again
