Things You'll Need
New pull cord with handle
Wide-jaw vise grip pliers
Lighter or matches
Most Ariens snow blowers are built using Tecumseh horizontal-shaft small engines. While some of these engines employ an electric starter, many are started using a pull cord that rewinds around a spring-loaded pulley. Since the snow blower is often exposed to harsh elements, the pull cord can often deteriorate and break. Replacing the pull cord on an Ariens snow blower is a relatively simple task that can be done in moments with a few basic hand tools.
Disconnect the spark plug wire from the spark plug by pulling on the rubber boot that covers the tip of the spark plug.
Loosen the three bolts that secure the starter shroud to the engine. Pull the starter shroud off the engine, and place it upside-down on a work table.
Hold the starter shroud with one hand, and turn the pulley in the center of the shroud counterclockwise until it stops turning. Clamp the pulley in place using a pair of wide-jaw vise grip pliers.
Grab the knot in the knothole near the center of the pulley with a pair of needle-nose pliers, and pull out the broken section of cord.
Insert the end of the new cord into the hole in the outside of the starter shroud. Guide the end of the cord into the pulley toward the knothole. When the cord appears in the knothole, grasp it with the needle-nose pliers and pull out about a foot of slack.
Tie a knot in the end of the cord. Singe the remaining end of the cord with a lighter or match to prevent fraying.
Pull on the cord from outside the starter shroud until the knot seats firmly in the knothole. Release the wide-jaw vise grips and allow the cord to recoil around the pulley.
Replace the starter shroud onto the engine. Tighten the three bolts, securing the shroud in place.
Reconnect the spark plug wire onto the spark plug.
Always use starter cord that is approved for use in small engines such as your snow blower.
When working on a small engine, always disconnect the spark plug wire before you begin, to prevent accidental firing of the engine.
