How is oil getting into carburetor?

Oil can enter the carburetor due to several factors, such as a worn or damaged engine component, like piston rings or valve seals, which allows oil to leak into the combustion chamber. This can lead to oil being drawn into the carburetor during the intake stroke. Additionally, excessive crankcase pressure can push oil vapor through the breather system into the carburetor. Lastly, improper tuning or flooding of the carburetor can also contribute to oil accumulation.
