Ok guys I'm having an issue with my mower not getting fuel. I have replaced all the fuel lines, taken carburetor part and sprayed carp cleaner throughout the whole thing so I know all ports are open. I have cleaned the stater and the fly wheel. I am getting spark and fuel is getting to the carb bowl but will not go any further than that. The engine is a Briggs and stratton 406777. Any assistance will be appreciated.
