I have a mid 2000s briggs and stratton vanguard 16 hp that will not run.I have changed the plugs, changed the air filter, fuel filter and 3 different fuel pumps. I've cleaned out the carburetor, and even replaced the gasket on the valve cover, thinking that I wasn't getting a good seal and was losing vacuum pressure to run the fuel pump.When I spray starter fluid in the intake it starts and runs, and when I manually full the carb with gas it runs, until the fuel is gone.
What am I missing?
