The key comes with this Briggs and Stratton Vanguard V Twin. This a 20 hp motor and starts right up every time with manual choke pulled out-on 2nd Pull. Then immediate push choke lever back in. Garage kept since I bought it in 2017. I have maintained this Mower since the day I bought it and it has not let me down. I had to install a new pull string. I have changed the oil with 30w oil routinely about once a year. I used non ethanol fuel in her but it will run fine on regular unleaded. I replaced the front tires to solid rubber. Both of the rear rear tires are a few years old but in very good condition. Brand new deck belt and blades. Everything is manual. Runs and cuts excellent. I manually set the blade height to 2 inches for my yard. Please text me or use the CL email
