try adjusting fuel intake on the side of carb. just unscrew it a hair and you should be fine.

Clean ALL the very small holes in the brass bolt that holds the carb bowl on.Some are VERY small and easily clogged. With bowl off and the bowl float hanging free, does gas readily flow? It should, and it should of course stop when the float is raised (putting the needle valve on its seat). If this event is occuring, then the main jet must be badly clogged. If no gas even gets into the bow. (not enough details).. then there is a vacuum lock or something strange going on in the fuel tank (cap). The threads of the fuel cap on a mower allow it to vent, preventing vacuum lock of the fuel flow.Start at the tank and go back in. Please repost as this is a good one.

This is probably not a blown gasket issue. A bad head gasket can allow oil to enter the cylinder head/combustion chamber if it's not sealing off the valve area. A simple suggestion is to check on the engine opposite the carb side for the oil/crankcase breather. It will have 2 screws holding it onto the block. It has a type of filter media in it that traps excessive oil and oil vapors from the engine. It is also connected by a tube to the air filter housing. When you tipped, you probably put too much oil in the breather and it was inducted over to the air filter/carb intake side.
Clean or replace the breather after checking it and also make sure you haven't overfilled the Briggs with oil and only use SAE 30 in the engine. Muti-viscosity isn't recommended in summer unless you run synthetic, then it is OK.
Please vote on this solution.

Sounds like the float valve is sticking open. You will have to drain the gas (or at least turn off the valve where the gas leaves the tank if so equipped.) Then remove the bowl to clean the float valve. (There is usually a nut in middle of the bowl.) The bowl looks like a bowl, and is about 2 inches in diameter. When you remove it you will see the float, which probably looks like a little brass donut. If you remove the hinge pin that allows the float to move up and down (it only moves about 1/2 inch) you will then allow the valve pin to fall out. The valve pin is about 3/4 inches long and maybe 3/16 diameter. (I am not measuring these things, just giving approximate dimensions so you will recognize them when you see them.) Good luck, Al K

there should be a little screw to help adjust your idle try that..counterclockwise to add more idle, clockwise to slow idle..
