Leakage can also be caused by the corroded carburetor or because of the gasket, which is not fixed properly. Make sure to get the carburetor which is made up of a hard body, to avoid any corrosion or leakage.

9. Body and Parts

There are different parts of a carburetor that work in combination to regulate the proper combustion process that is required to run the engine. Different parts of a carburetor are, a main running jet, a venturi-shaped airflow restriction, an accelerator pump, a choke, the storage chamber for liquid fuel, and an idling that is a slow running jet.
