Where can I find a starter for this lawn mower

@atstransmi85906 we need the information for the engine. I believe it's a B&S but they used a variety of different models and engine sizes from 15hp to 18hp. Decals are always good and I suspect your mower is an LT4216 or 4218 which would make it a 16/18HP engine Any numbers on the engine will help. Even pictures will help Adding images to an existing question

REmember, the K-Gro was a K-Mart brand and the mower is actually a Murray/MTD mower
