could be the priming bulb gasket between the air-filter assy. and the carb.
I have the same lawnmower and if I prime with gas from a can it will start but stop after a few seconds. When I push the bulb I can hear air leaking in this area. You can replace the gasket by removing the back half of the air-filter assembly. I am looking to buy a gasket today I let you know how it works out! Thanks Ron
The fuel bowl has a float and needle, the bowl is filled with gas and over time the float gets filled with gas or just don't float as it should within the bowl. the needle is pulled up by the float which lets fuel flow into the carb. A repair kit can be bought for $5 and is easily replaced. After you take this apart, it's a good idea to clean the carb with a carb cleaner. You'll have to take off quiet a bit which looks difficult but it's really not.
The float and needle need replacing. Take the carb off soak in a high octane gas or booster for 15 min. The float isn't floating in the gas bowl, which rises the needle to let more fuel in. When you prime the carb, you are directly shooting gas to the carb, this is why it will start and then shut down because the float can't keep gas flowing in. A kit cost about $5-7 and easy to replace.
If this is a prime type carb then the carb need cleaned and a new needle and seat installed. It starts and almost immediatley stops indicates its running on the primed fuel only. Some models of briggs engines do have a auto matic choke. I doubt if its this one. Please indicate engine model and type numbers which are located on the front of the blower housing or on a tab that sticks off the side of the blower housing.If I had these numbers I could determine if your engine has a auto choke
often the last ounce of gas in the tank has some crud in it. Get a can of carbeurator cleaner spray. Remove the air filter and squirt three short bursts of the cleaner spray into the air port and then start it. Keep giving it short bursts of carb. cleaner until it runs smoothly again.
The jets in carbs are really small and clog easily. If you stored your mower with gas in it start by replacing the gas. Remove the air filter and prime the carb. Start the engine and place your fingers over the air intake on the carb. This will cause the engine to stall as it will be starved for air. It will also create a powerful suction on the jets and possibly dislodge a blockage. Prime the engine again and start. If does not continue to run, repeat the steps again. If after 3-4 tries your engine wont run you will have to remove the carb and clean the jets manually. The reason your engine runs for a short time is because it is burning the fuel that you put in there by priming it. After that the fuel comes through the jets in the carb and if these jets are clogged the engine will die.
