HI there, I got a lawn mower mtd yard machine briggs ans stratton 4,5 hp, it start pretty well but won't stay running, I change the spark plug, oil, gas brand new, clean the carburator, clean the air...
There could well be a build up of sediment and debris in the main jet to the carburetor. It is easy to get to and clean. It is the brass bolt that holds the lower float bowl onto the main body of the carburetor. To clean it, drain your gas. Remove the bolt and external washer UNDER the carburetor bowl. Clean out the bowl of any sediment and/or water. To clean the brass bolt, use no metal objects. Carb/Choke aerosol spray cleaner will do the job. Pay close attention to the hole in the bottom of the bolt and the very small holes about 2/3 of the way up the bolt. Clean till shiny with holes cleared and reinstall. Your fuel flow problem and shut off condition may be solved.
