Model 917.203900 25hp Briggs intek v twin. stumped, mower worked fine 2 wk ago now fuel delivery not working. Fuel pump good squirts output side when cranking. Fuel Solenoid good pulls in when turned to start, took carb out and cleaned jets etc, nothing was stopped up altho very gummy in the bowl. Gas is a few days old as a mow weekly in the summer. Starts the immediatly stalls on starter fluid, can keep spraying to keep running. Just fyi spark plug tester indicates spark. Trying to cover all bases. Venturing hose hooked up and pretty new. Replaced earlier this summer. Tried with gas cap off. Bowl fills with fuel. I do have a 18mb video no starter fluid but it will not let me attach file.
