I have a MTD 12.5 hp & it has a red & black wire with a plug coming out behind the starter going to the stator I need to know where that plug goes to. I also need to see the linkage for the carburetor linkage. The motor model is 289707, the type is 0154 01, and the code is 940505 4D and it's a 12.5hp. Can you find any riding mowers made by MTD with this motor? Thanks Jim
