17 hp Briggs and Stratton Intek governor and oil blow by issue

I have a 17 hp Briggs & Stratton Intel ohv riding lawn mower engine. Model 31F707. The governor has stopped working. It stays on a high rev and oil fills the carborater via the crank case breather tube. Does anyone know what is causing these problems?

You need to start by resetting the governor. This manual will show you how.
