It's important to note that attempting repairs to your Cub Cadet snow blower without finding the cause of the issue may bring additional harm to the machine.

In this section, you'll know the possible reasons why your snow-blowing machine fails to start after being in storage during summer.

Read through this section to help you formulate a plan to increase the likelihood of restoring your snow blower's normal functions.

Bad Spark Plug

A snow blower's spark plug is generally responsible for igniting the fuel in the machine's motor. If the component is in good working condition, it should allow the engine to start.

But the spark plug can be vulnerable to harm. This damage can come from different sources, including dirt, carbon, grease, and outside debris.

Aside from the Cub Cadet snow blower not starting, other signs of a bad spark plug to watch out for are:

  • Rough idle
  • Engine misfires
  • Engine stalls
  • Unusually high fuel consumption

How To Fix

Cleaning or replacing the spark plug are two options that you may take advantage of to fix your Cub Cadet snow blower. Try cleaning the spark plug to check if this method solves the problem.

If not, you may need to replace the worn component with a new model.

Take note that you can typically find a Cub Cadet snowblower spark plug at the front or top of the engine. Also, specific models may have more than one spark plug.

So it can be a good idea to check each spark plug in your machine for possible defects.

Follow these general steps to clean and maintain your Cub Cadet snow blower's spark plug:

What You'll Need

  • Ratchet and socket set
  • Metal wire brush
  • Carb cleaner

Step-By-Step Guide

  1. Ensure that the engine is off.
  2. Hold the boot at the end of the wire connected to the spark plug.
  3. Pull the boot to disconnect the wire from the spark plug.
  4. Rotate the spark plug counterclockwise using a ratchet and socket to loosen it, and you can remove it.
  5. Use a carb cleaner to remove dirt and carbon buildup on the spark plug.
  6. Lightly brush the part's surface with a metal wire brush to help remove serious dirt and carbon accumulation.
  7. Return the spark plug to its original location in the machine.
  8. Reconnect the wire to the spark plug.
  9. Attempt to ignite the snow blower's engine to check if the problem persists.

Note: Although it's possible to clean a spark plug and achieve appropriate results, Cub Cadet doesn't recommend cleaning the part. Instead, replacing the worn spark plug with a new unit might be safer and more cost-effective.

Expired Fuel

Take note that fuel can expire and lose its usefulness in about 30 days. Plus, you may only use your snow blower for a few days in the winter.

If you leave fuel in the snow blower's tank for almost an entire year, it may not provide sufficient starting power for the engine to ignite.

How To Fix

Draining the old fuel and replacing it with a new batch should allow the Cub Cadet snow blower to work correctly again. Generally, you only need a siphon pump and a fresh batch of fuel for this procedure.

First, attach the siphon pump to the snow blower's gas tank. Then, request help from another person to tilt the snow blower. That way, the fuel should start escaping through the hose.

After removing all the old fuel in the tank, refill it with a fresh batch. Don't forget to remove the siphon pump from the tank and close the container. Try to ignite the snow blower's engine to check if it can start as intended.

Stuck Valve

Snow blowers often have different valves, such as the engine valve. If you leave a valve open as you place the machine in storage, it might remain in that position after removing it from the space.

Note that certain valves need to close for the snow blower to function.

How To Fix

Try closing the open valves manually. But if it's challenging to complete a valve, even if you're using a significant amount of force that you can muster, follow these steps:

What You'll Need

  • Borescope
  • Penetrating fluid

Step-By-Step Guide

  1. Feed the borescope into the snow blower to search for the stuck valve.
  2. Apply penetrating fluid in and around the stuck valve.
  3. Allow the penetrating fluid to set according to the product manufacturer's instructions.
  4. Try to turn the valve to its closed position.
  5. If successful, attempt to turn on the Cub Cadet snow blower if its engine starts.

Check out this borescope on Amazon.

Note: You may need to take some parts of the snow blower apart to find the stuck valve. Use this option if you can't find the offending valve with the borescope.
