Why does a Briggs and Stratton lawn mower throw oil in the exhaust and carburetor?
Wiki User
∙ 14y ago
The intake valve is not closed deep enough into the valve seat due to being too long and crankcase pressure is allowing some oil from the engine to be sucked up the valve guide into the combustion area and the 4 cycle process allows some of the oil to be pushed into the intake cycle and thus gets into the carburetor intake area and then into the exhaust system as the engine completes the cycle.
Can also be caused by the mower turning over or when the engine oil level too high.

Who does Briggs and stratton contract to build their snapper mowers?
Briggs and Stratton does contract anyone to build mowers. The mower manufacturers contract Briggs and Stratton to build their engines (or whatever engine is on the unit). That is why you can have a Briggs and Stratton on most any type of mower. Same is true for Kohler, Tecumseh, etc. Not to say that the engine manufacturers do not build their own type of outdoor power tool but as the question states "snapper mower". Also keep in mind that if you have a snapper mower with a Briggs and Stratton engine and you need warranty work on the engine you need to go to an Authorized Briggs repair facility where as if you have a mower warranty then you need to go to an authorized repair facility for the mower manufacturer.
