  Christopher MercadoAug 7, 2025
  There are several potential reasons why your Ariens Snow Blower engine might not crank or start: * The fuel tank could be empty, so ensure you fill it. * The fuel shut-off valve might be closed; make sure it's open. * There might be a buildup of dirt and residue around the governor/carburetor, so clean that area. * The key switch may not be in the run position; put it in the correct position. * The electric starter could be malfunctioning; check for a bad starter or loose connections.

  If your Ariens Snow Blower isn't throwing snow well or at all, consider these possibilities: * The shear bolts might be broken; replace them. * The attachment clutch/brake may not be adjusted properly; adjust it. * The impeller could be frozen in place; move the unit to a warm place to thaw it. * Ice or debris might be obstructing the auger; with the engine off and the auger disengaged, check for and remove any obstructions. * The attachment drive belts might be slipping, worn, or damaged.

  Your Ariens Snow Blower engine may stop due to several reasons: * You might be out of fuel, so refill the fuel tank. * The fuel shut-off valve could be closed; open it. * There might be a mechanical jam in the blower rake or impeller. If so, turn off the engine, remove the key, wait for all moving parts to stop, and then check for and remove any obstructions before restarting. * The fuel supply could be polluted; replace it with clean fuel. * The spark plug might be faulty; replace or clean it. * The fuel cap vent could be plugged; replace the fuel cap.

  If your Ariens Snow Blower runs briefly and then stops, it might be due to a buildup of fumes in the fuel tank creating too much pressure. Carefully loosen the fuel tank cap to relieve the pressure.

Why are there small rubber beads collecting in the frame of my Ariens Snow Blower?

  The small rubber beads collecting in the frame of your Ariens Snow Blower are likely due to normal friction disc wear. However, if you notice chunks or large pieces of rubber, you should check the friction disc and replace it if necessary.
