How to fix Ariens Sno-Thro ST20E Snow Blower engine that will not crank/start?

  Rebecca KennedyAug 11, 2025
  If your Ariens Snow Blower's engine won't start, there are several possible causes. First, ensure the fuel tank isn't empty by filling it. A buildup of dirt and residue around the governor/carburetor can also prevent starting, so clean that area. Make sure the key switch is in the run position. Finally, if you're using an electric starter, check it for bad connections or a faulty starter.

  Christine MoralesAug 19, 2025
  Your Ariens Snow Blower engine may stop for several reasons. Check if you're out of fuel and, if so, fill the fuel tank. A mechanical jam in the blower rake or impeller can also cause this; turn off the engine, remove the key, wait for all moving parts to stop, and then check for and remove any obstructions before restarting. A polluted fuel supply might be the culprit, so replace it with clean fuel. Lastly, a faulty spark plug can cause the engine to stop, so replace or clean the spark plug.

  If your Ariens Snow Blower isn't throwing snow well or at all, several issues could be the cause. Start by checking if the shear bolts are broken and replace them if needed. Another potential cause is that the auger is frozen in place; move the unit to a warm place to thaw it. Also, check for ice or debris obstructing the auger and remove any obstructions with the engine off and auger disengaged. Finally, the attachment drive belt might be slipping, worn, or damaged; in this case, adjust or replace the attachment drive belt.
