A lot of time when the small motors on these push mowers surge it is a governing spring that is weak or broke. It does not hold enough tension and causes the valve to fluctuate. I have fixed this many time for a relatively cheap amount (under $5).

computerscot is right. This engine is not designed to run slower than a few hundred RPM below maximum. The carb has a built-in fuel pump that only operates properly at relatively high speed. Your motor probably has either missing or weak throttle springs which will lower the RPM. Replace them and adjust the tension so that the speed is up. For a diagram of the carb and springs, check the Briggs & Stratton online user manual maintenence section. Look for file "briggsandstrattonMS5373-GB.pdf".

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.
