A two-cycle motor, such as those on a Craftsman chainsaw, utilizes a carburetor connected to the fuel tank to blend air into fuel before sending it to the motor. The gas lines, that run between the tank and carburetor and back, may get cut, decay or become clogged with use and time. Replacing the lines is simple and requires no specialty gear.
Drain any fuel from the fuel tank to your gas can. Unplug the spark plug and cable. Unscrew the main cover of the spool and then pull it off. Also, unscrew and remove the air filter cover and starter assembly. Slide the old fuel lines from the carburetor, that need to be clearly reachable. Pull the fuel filter and fuel lines from in the gas tank using pliers.
Cut one end of both sizes of tubing to a 45-degree angle together with the scissors. Feed this finish into the gas tank and pull the lines with the pliers until the angled finish comes from the top of the tank along with the other end hangs from the small holes you fed them through. Cut the angled ends straight.
Attach the gas filter to the newly straightened end of the line. Slide the hose matching on the larger hose. Pull the seams back through the smaller holes with the pliers so the fitting and filter are tight to the tank and create a seal.
Measure the distance needed to get the fuel lines to the carburetor and then cut on the lines straight. Attach the smaller hose to the gas pump side and the larger hose to the bulb tip area.
Replace the starter assembly, air filter and cover. Plug in the spark plug boot and wire.
