  Your Ariens Snow Blower engine might stop for several reasons: it could be out of fuel, so check and refill the fuel tank. There might be a mechanical jam in the blower rake or impeller; in this case, turn off the engine, remove the key, wait for all moving parts to stop, then check for and remove any obstructions before restarting. A polluted fuel supply or a faulty spark plug can also cause the engine to stop; replace the fuel or clean/replace the spark plug to resolve these issues.

  If your Ariens Snow Blower engine won't crank or start, there are several things you can check: * Ensure the fuel tank isn't empty and fill it if needed. * Inspect the area around the governor/carburetor for any dirt or residue buildup and clean it. * Verify that the key switch is in the run position. * If you're using an electric starter, check for a bad starter or faulty connections.

  If your Ariens snow blower isn't throwing snow well or at all, consider these potential causes: * Broken shear bolts: Replace them. * Improperly adjusted attachment clutch/brake: Adjust it. * Auger is frozen: Move the unit to a warm place to thaw it. * Ice or debris obstructing the auger: With the engine off and auger disengaged, check for and remove any obstructions. * Slipping, worn, or damaged attachment drive belt: Adjust or replace the attachment drive belt.

  If your Ariens Snow Blower isn't moving forward, it could be due to a traction drive cable that isn't properly adjusted or a traction belt that isn't functioning correctly. You should adjust the traction drive cable or repair/replace the traction drive belt.
