Removed motor from lawn tractor frame. I had watched donyboy repair video on utube & a few others. Then copied what they shared on the video.
Put everything back together in reverse order. Then fixed the carburetor and reinstalled it.
Remounted motor back on the tractor, double checked everything again.
Put fuel back in tank then started, it started right up and runs wonderful now. Saved a lot of money doing it myself. You should do it. It was not that hard at all.
I would do it again for sure. Order parts from e replacement parts.com they get parts out fast.
And price was fair.
