Place the snowblower on a level surface, such as a driveway, or garage floor. Locate the engine of your snowblower. On Bolens models, the engine is typically between the snow intake auger and the handle you use to push and guide the machine.
Stand behind the handle. The carburetor is generally located above the left wheel. View the engine from the top and then identify the choke and throttle control knobs. The carburetor is enclosed within a metal cover, which is located to the left of the muffler and the spark plug.
Remove the metal cover, using either a screwdriver or Allen wrench, depending on the model of your snowblower.
Set the cover aside and identify the carburetor. It is attached with bolts to the side of the engine and has a gas line and air cleaner attached to it.
