When you take off the carburetor initially, you should change the gasket if it tears or just old looking, your problem is in the carburetor, probably. Take it apart remembering where the parts go. There are some diaphragms or gaskets and screens on some, tiny jets and such that are inside the little "bulb" or bowl, that can usually be taken off with a 10mm wrench. They also have little fiber gaskets and a bowl gasket or o-ring that must be in great condition with no trash. Clean off with starter fluid or carburetor cleaner.

SOURCE: briggs & stratton with idle problem

This is not unusual at idle; there is a governor to limit maximum RPMs and this device isn't worth beans at an idle.
You may be able to carefully adjust the idle adjustment (see your manual or B&S website) to achieve a somewhat more even idle speed.

Could be float in carb.sticking.Take carb off & apart.Put float in water to see if it floats.Check float by shaking next to ear.If you hear any sound,you need a new float.

SOURCE: Briggs & Stratton Modle# 100000 will not stay started.

your engine is only running on the fuel you are pumping in, the carb. is not lifting the fuel on its own, maybe because of water in the bowl or dirty jets. You must take the bowl of and clean it out and depending on the type of carb. it might need a new diaphragm. Stephen.

Have a Briggs and Stratten 4.0hp Lawnmower that starts but sputters. What can I do to get it running smooth...What is the Spark Plug GAP?


How old is the fuel? Drain old fuel, use premium fuel and change spark plug and maybe air filter. I start mine in the Spring using quickstart. It also starts and dies a few times and eventually keep running. Winterizing the machine in the Fall prevents most starting problems in the Spring. If this does not solve the problem, see a mechanic.

3.5 hp Briggs & Stratton won't run unless I pour gas into carb


This sounds like a problem with the suction. If the air filter is clean then it will need new carb gaskets. There may also be an issue with the pressure being created by the engine.

Pull cord wont pull,briggs 500 series


Pull the spark plug out and see if it isnt hydro locked. Someone might have overfilled the oil or the carb float may have stuck open and filled the intake with gas!

If the recoil is still stuck you can remove it from the mower and try it without any load on it. Still stuck? The unit might be rusted solid!
You can spray a little penetrating oil into it but be careful.....the oil will soak the pull cord which should be cleaned and degreased immediately following using the penetrating oil.

I hev a briggs & Stratton 5.25hp lawnmower and


I would need the engine numbers to tell ya what to do for sure. It sounds like the engine is too full on oil. Check oil levels carefully.That engine capacity is only 1 pint/16 to 20 oz's ALSO you friend may have cleaned under your deck and turned the mower with the aircleaner DOWN. That causes oil to flow from the crankcase into the air cleaner and muffler.That aircleaner is a dry paper and should not have any oil on it, If this is the case then the oil accumulated in the muffler will burn off in time. Oil soaked paper aircleaners will cause this engine not to start.IT CANT BREATH

5hp Briggs & Stratton lawnmower starts but stop running?


Try cleaning the air filter, and check fuel tank for any debris.
Replace fuel filter if there is, and give the fueltank a good cleanout.
Use fresh fuel to refill.
