Engine doesn't seem to be getting fuel
I have a Sears 6.5hp Briggs & Stratton mower that will not stay running. To start the mower there is a button that is to be pushed 3 times and then pull the cord. The mower starts and then dies. If the button is pushed several times the mower will run longer. It appears to not be getting gas. Thinking there was a carburetor problem I replaced it. no change. The fuel flows freely from the fuel line when pulled from the carb. Any ideas on which way to go?
