Product Description

?

This is an Original Manufacturer Approved Carburetor Assembly used on Weed Eater Handheld Blower. It has a Metal Body with Plastic Levers. This carburetor is Sold Individually. The purpose of this part is to mix air and gas before the fuel mix goes to the engine. If the engine won't start and the tank is full of fresh fuel, test the carburetor by removing the air filter and pouring about a teaspoon of fuel into the carburetor. Pull the starter rope. If the engine starts and then quickly dies, the carburetor is likely the problem. It is advised to replace Gaskets (Sold Separately) when replacing the Carburetor.
