CARB ASM AC8 753-08057

This genuine replacement part is designed for use with Troy-Bilt trimmers. It is sourced from original equipment manufacturer and it 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. To complete this repair you would need a screwdriver.
