Ariens Snowblower Runs Rough – Know What An Expert Do


A snowblower is a great way to clear snow from your driveway or sidewalks, but if it’s not running properly, it can do more harm than good. If your Ariens snowblower is running rough, it’s important to look at the engine and ensure everything is in good working order.

A rough-running engine machine can damage the parts of the engine. It can also cause the snowblower to emit more pollutants into the air.

The carburetor and spark plug of the snowblower might be the major cause of this problem. If you’re unsure what to do, read this step-by-step guide to repair your rough-running Ariens Snowblower.

Ariens Snowblower Runs Rough

If your snow-blowing machine is not running great or surging or pulsating then see the below guide to solve this issue.

1. Inspect The Spark Plug

If your Ariens snowblower runs rough, it could be caused by a dirty or fouled spark plug. A spark plug is a critical component of the engine, and if it is not functioning properly, it can cause several problems.

Over time, the spark plug can become fouled with carbon deposits, which can lead to poor engine performance. A fouled or dirty spark plug causes the engine to run rough, and it can also lead to engine damage.

If you notice that your Ariens snowblower runs rough, the first thing you should do is inspect the spark plug. You will want to look for any erosion on the electrode. If there is erosion, it means that the spark plug is not firing correctly and needs to be replaced. You will also want to look for any carbon build-up on the plug. Carbon build-up can cause the spark plug to misfire.

Now, we will discuss how to inspect the Ariens snowblower spark plug and what to do if it is dirty or fouled.

How To Clean and Test Or Replace A Spark Plug?

It is important to know how to inspect, test, and clean your snowblower spark plug. Neglecting to do so can cause your engine to run less efficiently, use more fuel, and produce more emissions. In extreme cases, it can even lead to engine damage.

Here is a quick guide on how to inspect, test, and clean your spark plug:

  1. First, remove the spark plug from the engine. You will need a spark plug wrench to do this.
  2. Once the spark plug is removed, take a close look at it. Look for any damage, such as erosion or carbon buildup. If you see any bodily damage, it is best to replace the spark plug.
  3. If the spark plug looks in good condition, you can test it to see if it is still good. To do this, you will need a spark plug tester.
  4. For testing, first, attach the ground (black) clip of the tester to the spark plug. Then, touch the tip of the tester to the metal part of the spark plug.
  5. If the spark plug is good, you will see a good spark. If you don’t see a spark, or if the spark is weak, then the spark plug needs to be replaced.
  6. If the spark plug is good, you can clean it and put it back in the engine.
  7. To clean it, use a wire brush and some solvent. First, remove any dirt or debris from the spark plug with the brush. Then, soak the spark plug in solvent for a few minutes.
  8. Finally, rinse off the solvent and dry off the spark plug before reinstalling it in the engine.

2. Inspect the Carburetor

If your Ariens snowblower runs rough, one possible issue is the faulty or clogged carburetor.

The carburetor is responsible for mixing the fuel and air in the engine, and if it is not working properly, the engine will run rough, or maybe your Ariens snowblower will only run on a choke.

Over time, the carburetor can become clogged with fuel residuals and gunk, which can cause it to run less efficiently. Luckily, this is an easy problem to fix. Simply inspect and clean the carburetor if necessary.

To inspect the carburetor,

  • first, make sure that the fuel is fresh and that the carburetor is getting adequate fuel.
  • Next, check the air filter and clean or replace it if necessary.
  • Finally, look at the carburetor itself and clean it with carburetor cleaner if needed.

If you have inspected the carburetor and made sure that it is clean and functioning properly, but the snowblower still runs rough, there may be a problem with the engine oil.


We hope after reading the above guide you will be in a great position to repair your Ariens snowblower that runs rough. Thanks for reading!
