What causes oil to leak from carburetor?
A blown head gasket is the most expensive and damaging cause of oil coming out of your carburetor. However, the most common cause of a head gasket blowing out is that the mower is overheated from too much use. Too much heat leads to expansion inside of the Briggs and Stratton mower, and that can blow the head gasket.
