How to Clean a Fuel Line in a Troy-Bilt Mower

Running between the carburetor and the gas tank on a Troy-bilt mower is the fuel line. The fuel is drawn through the fuel line and into the carburetor. Inside the carburetor the fuel is mixed with air to create well-balanced combustion. If the fuel line of your Troy-Bilt mower is blocked, the fuel mixture will have too much air in it, which may cause the mower to sputter or stop working altogether.
