My Chainsaw Is Not Getting Gas

One of the most common problems on a chainsaw is insufficient gas delivery to the carburetor. The carburetor needs a specific amount of fuel to fire the gas and move the piston in the cylinder. Many chainsaw owners are unaware that leaving gas in the fuel tank for more than two weeks will cause this problem. The gas will start drying and as it does, it will leave behind a sticky residue that chokes the carburetor.
Things You'll Need
Fuel container
Brush
Rag
Screwdriver
Needle-nosed pliers
Metal wire (baling wire)
Scissors
Replacement fuel line
Replacement fuel filter
Remove the cap to your gas tank. Dump all of the old fuel into the fuel container. Wrap the rag around the brush and scrub the inner walls of the tank. Pour a little gasoline into the tank. Close the cap and swish it around for 10 seconds. Open the tank and dump the gas out. Clean the tank again with the brush and rag.
Open the top cylinder cover using the screwdriver to remove the -- most often -- four screws holding the cover in place. Lift the cover up; slide the air filter away from the mounting plate. Look to the right of the air filter and locate the two fuel lines. The top, closest to you, is the main line. The bottom is the impulse or purge line.
Grab the top line closest to you with the needle-nosed pliers and disconnect the tubing from the valve on the carburetor. Tip the engine upside down and shake it a little. Watch to see if a few drops of gas exit the tubing. If no gas is present, replace the fuel filter and fuel line. If gas is present, your carburetor needs to be cleaned and serviced. Leave the carburetor repair to professionals.
Reach into the tank with the metal wire and hook the fuel filter and fuel line, bringing them upward to the tank opening. Grab the fuel line and pull the filter and line out through the tank. Cut off a 10-inch section of tubing for the new fuel line.
Stick the metal wire into the tubing and push it through the hole at the bottom of the tank. Grab the fuel line when it pops out near the carburetor with the needle-nosed pliers and pull it toward the carburetor. Take the metal wire out. Put down the new fuel filter by sliding it into the tubing’s end. Push them down into the tank’s bottom.
Hook the line back up to the carburetor with the needle-nosed pliers. Reattach the air filter and cover. Fill the chainsaw with freshly mixed two-cycle gasoline and try to start it. If it still doesn’t start your carburetor will need to be cleaned and serviced. Carburetor repairs need to be handled by professionals as you can damage your engine.
