moves then dies like not getting enough fuel.

Enough fuel in the tank? Clogged filter? Fuel lines can go bad also, internally they can flake apart and clog. Try taking off the line at the carb or pump and see how much fuel comes out.

check to see that it has spark on both cylinders. I had the diode wire on a 18 vanguard burn out killing one cylinder. it acted a lot like what your describing. if it doesn't have spark on one side, pull the flywheel cover and remove the small black wire running between the 2 coils. then fire it up and see how it does. with the wire removed it won't shut off with the switch, you will have to choke it to kill the engine. you can do a SHORT test drive with the flywheel cover removed, but that is what directs cooling air to the cylinders so don't hammer on it too hard or you risk burning up the engine. a new kill wire is around $11 from any briggs dealer. they will want the model, type, and code (stamped on a tag on the flywheel cover) to look it up.
