Customer Question

I have Series 500 158cc lawnmower.The engine will start easily enough after priming but only for a couple of seconds after which it cuts out.If you prime it again it starts but again cuts out.Obviously some problem on the fuel supply but where do I start?

When did it last run? Remove the carburetor bowl and see if the float is moving the needle valve, when needle valve drops with float,fuel should enter the bowl. I assume you have fuel to the carburetor. Here is a basic Briggs carburetor link. ---http://outdoorpowerinfo.com/repairs/briggs_walbro_lms_carb.asp
