carburetor parts (such as main jet) oil path and float chamber surface. The air enter into the
carburetor through air filter, based on the intake can not be too much resistance and other
factors to consider, the filter can not be too dense and therefore part of the air in the tiny
impurities will enter into the carburetor through the air cleaner.
