Hi, I have a Cub Cadet XT1 riding mower it has a Kohler 18hp motor it has 35 hours on it and Im having a problem and would like to get some help if possible. The lever that chokes the carburetor does not work, it does not move at all so when I move the lever to either choke or put it in fast or slow speed it does nothing. It does drive but only in slow mode, the choke remains open unless I manually move the linkage by hand. It is still under warranty but the TSC store that I bought it from says they dont know if the warranty will cover it and they will have to send it out. I dont know how this happened because it was running fine until I went to use it after winter. I am wondering If I can fix this myself because I dont have the money to pay for repair if warranty doesnt cover this.
