i have a murry lawn mower with a 5 hp briggs and stratton that is 2 years old. when i start the mower it will get up to normal rpm for about 1-2 seconds and shut off. i have fresh gass in it, oil level full and a new air filter. i use a small bit of seafoam in the gas every so often to keep the carb clean. it seems to be a fuel cutout but i dont see a filter anywhere. anyone have any advice on what i should do next??????
*** i have worked on cars for 11 years now and small engines are a bit new to me. i have way too much man pride to take such a simple engine to a repairman so you can kindly save those types of replies.

These B&S engines are pretty simple, so if you think there is a fuel problem there are really only a couple of things that could be wrong: clogged fuel line (unlikely), clogged carb, or stuck float. The carb is pretty simple and even a non-gearhead like myself was able to figure it out. There are only a cope of pieces to it and it is easy to figure out what could get clogged once you get it open. The float is a little piece of plastic that regulated the gas flow into the bowl, so if it gets stuck gas flow will be slow or stopped.

Take the engine model number and go to the small engine shop and pick up a rebuild kit for the carb. I have run into several briggs carbs where the diaphram is bad on newer engines. Clean the carb with a good parts cleaner making sure all the passages are open, check the fuel tank for debris and put it back together with the rebuild kit. It is an easy job and it will run like new.

I'm pretty sure your talking about a Briggs motor where the carburetor is mounted directly to the fuel tank with 5 screws. Where th carburetor and the tank meet there is a diaphragm that pumps and meters fuel flow. This diaphragm gets distorted very easily by bad gas and water. when this happens it needs to be replaced. The good news is it's one of the easiest repairs to do. The kit is less than 5 dollars and you don't have to worry about fuel lines because this carburetor doesn't have any. The diaphragm sits on the tank and the carburetor sits on top of it and gets screwed down. Just make sure you dump all the old fuel out of the tank and flush it out good and don't use anything other than fuel stabilizer.

One thing I will advise you not to be doing is adding something to the fuel that does not belong...we have fule stabilizers for this..now, is your gas "fresh" as in you went filled your red jug up and then used it?..not that it sat in the jug in the garage or where-ever for God knows how long..put that gas in your car..small engines cannot handle bad gas..invariably, we know it when you bring them to us, as we can smell the old gas...no, matter what you say..we can tell that it is old gas..why we all go to our updates every year...we have to, in order to know about the new technology..Though we usually know before we go...but, there are things that we still learns on these babies everyday...I would suggest you take your model, type and code..then go to a shop or napa, sometimes carries this stuff...and give the info to them and get you a carb.kit..they aren't that expensive..but, check to make sure it isn't your diaphram, or maybe the needle isn't seating right, could be stuck, the diaphram could have a tiny hole in it...you can also get a full service kit for your mower at these shops that include everything..also, something people forget about on these..your spark-plug on occasion I have found a spark plug that will have a small crack and you can't see it..with an alternative light source you can..if you work on cars then you may have one of those little pocket lights that are blue?..use it to look at your spark-plug housing ....people tend to forget the easy things...make sure your fuel line isn't pinched..have seen that...and believe me, I have seen some doozies when it comes to people working on their own lawnmowers...people forget that they are small engines..Wish you luck....

I dont recomend using fuel stabilizer in gasoline, i find gasoline will be fine on its own in the mowers for at least one year, anything longer , get rid of it. Gasoline in itself is dirty, its filled with impurities right from the pump, then it sits in a gas can in your shed, settles out , till you dump it in your mower. The most common problem with non running motors is : the carburator. Id remove it ( taking notes/drawings where all linkages go) - disassmble , thoroughly clean it, inspect all gaskets , replace if needed. If theres any room to put a filter in somewhere, even a small one, itll help.

There is a good chance that the diaghram has a small hole or may even be cracked. It is in the carberator and is black looks like a little gasket.
It could also be the little bulb to pump fuel to the carberator before you start the engine may have a small hole.

Take it to a qualified repair shop and have them thoroughly clean and rebuild the carb. Do not put anything in the gas in the future in order to prevent the same problem happening again.
