    Briggs has gone with a plastic needle valve in the carb that is not heavy enough to drop out of the seat. Remove the fuel line from the pump outlet going to the carb. Apply about 30 psi blast of air to the line you took off the pump, this will dislodge the needle from the seat and allow fuel to flow into the carb ... GAS JUST AINT WHAT IT USED TO BE and a lightweight needle valve didn't help matters

A great expedient spark tester can be made from an old spark plug that you know is GOOD.....clip or grind the grounding terminal ( the terminal which goes over the top of the electrode) back until you have a gap of 1/8 to 3/16 of an inch between the terminal and the electrode...Remove both plugs from the machine and attach your new test plug to the plug wire. Ground the plug by placing it on the head or the shroud. Turn the machine over. If you are getting fire you should see a strong blue spark shoot from the electrode to the terminal. If you have no fire then you probably have a bad ignition coil, bad plug wire, or maybe just a bad seat, brake, or PTO safety switch...I'd check these first. Also check your ignition switch in the run position with a test light to be sure it is good....hope this helps... ;-D

Hi karen. Your not explaining what you have done to get the mower going. All petrol mowers run with three problems. Fuel,fire and air. If you are getting all three it will either be a snapped Piston or the gaskets on the block have perished. Check eHow's website and follow the instructions. Good luck
