Question: How Does Fuel Pass Through Weed Eater Carburetor?

Why is my weed eater leaking gas from carburetor?

The fuel in your weed trimmer must flow uninterrupted from the tank to the carburetor, from the carburetor to the cylinder, and all excess fuel must return to the tank. This cycle needs to remain completely airtight, otherwise fuel will start leaking from either the broken seal or from another area in the fuel system.

Do weed eaters have a fuel pump?

The gas is burned to power the machine, while the oil is used to lubricate the engine. But 2-cycle weed eaters only have one fuel tank where the oil and fuel are mixed together. As the gas is burned for power, the oil simultaneously lubricates the engine as it’s burned along with the gas.

Why does my weed eater keeps flooding?

The correct mixture of air and small squirts of gasoline combine in the combustion chamber to start the motor. Engaging the choke allows more gasoline into the chamber, which can flood the engine if you are trying to start it and it is already warm.
