I have a similar model. I'm not sure if yours is the same cheap chinese made hunk of quick rusting metal that mine is, but if it is I've had the same problem for a couple of years.
The only way I found to fix this is, every time I want to start it, empty the gas tank into a container and then take the float bowl off. You'll want a 10mm box end wrench to remove the bottom bolt from the float bowl. When you take it off, you should see lots of rust caked in the bottom of the bowl. Brush and rub that off with something smooth and hard (like the end of the wrench), after spraying with WD40 or similar spray lube.
Then spray the float itself, and you will see a small pin the float should be actuating (moving it up and down). Spray this pin, then gently tug on the float (down), and then release the float and gently push up on the pin itself. Once you get the pin to move, while pushing and pulling it and spraying it down with WD40, keep moving it until the pin automatically goes all the way up and shuts off the fuel flow, and the float smoothly comes all the way down. Then spray everything down really well with the WD40 and put it back together and put the fuel back in the tank.
It should run normally now, and any difficulties left should iron themselves out. At least until you sit it in the garage for a week and go out there to mow again, I have to repeat these steps every week and a half. One thing that seems to help is running the mower dry of gas every time before parking it in the garage, unless you'll be using it the next day or sometime very soon.
You might want to consider changing it over to use propane too, there are kits for sale on ebay that are supposed to do that really easily.

I can start my 4.75 HP Briggs & Stratton Lawnmower but it dies after a few minutes. I replaced the armature but the same thing happens. I can keep it running if I press the prime bulb a couple of times...


Try replacing the float and needle. The float (floats) and pulls the needle up to let gas through to the carb. It will stay running as long as you press the prime bulb because this sends gas straight to the carb without going through the gas bowl. It's best to remove the carb and clean it then replace the float and needle

Lawnmower starts and dies... where is the main jet for the carb?


try cleaning the air filter, then a touch of starting fluid right into the carburator by taking the air filter off. If it then starts but wont run or stay running, the reservoir below the carb should be removed to clean at and the pinhole in the intake tube above the bowl nut. This is the most common problem with lawnmower start problems, the pinhole can be unplugged with one wire from a wire brush. Be careful with the gas, at least pinch off the gas hose with a vise grips while removing the carb bowl.. Never use a droplight around gasoline. most lawnmowers have no mixture adjustments, so it is a matter of cleaning the carb, tank, gas lines. Some oils in gas mix systems settle and clog after less than one season.

If it then starts but wont run or stay running, the reservoir below the carb should be removed to clean at and the pinhole in the vertical intake tube above the bowl nut.

Spark can be tested by sight, remove the plug and use a clip-on ground wire from spark plug body to metal on the engine with the plug wire connected.

Wont stay running


Bad fuel or check for water in your fuel! Clean your carb and float bowl. Empty gas into a clear container, if there is two levels of liquid one of them is water. Of course make sure you have good spark plug.

Lawnmower will start but will not stay on


I had the same problem, what you need to do is adjust your throttle. To do that you there is a switch right in front of the filter. If you are looking right at it pull it all the way to left. If this dosen't work then check the springs that are connected to that switch they have a bad habit of coming loose. I had to replace all of my springs. Hope that helps.
