Home » How to Clean a Snowblower Carburetor

Carburetors are found in all kinds of internal combustion engines. A carburetor is the part of the motor where air and fuel combine at the correct ratio for combustion. Without a carburetor, your motor would be unable to run.

A snowblower carburetor is as equally important as the carburetor in a car or other vehicle, as it is essential to the motor receiving the fuel it needs, in the air-fuel ratio it requires to perform. Luckily, if your snowblower carburetor is not working properly, there is a good chance it just needs to be cleaned. Wondering how to clean a snowblower carburetor? Read on to find out more.

Dirty Carburetor Symptoms

There are many symptoms that may indicate that your snowblower has a dirty carburetor and it simply needs to be cleaned. Here are just a few possibilities that might indicate a dirty carburetor.

  • Your snowblower engine turns over, but will not start.
  • Your snowblower engine will eventually start but will have difficulty, most likely due to debris.
  • The engine is sluggish or jerks. This could be the cause of the engine running lean, due to an imperfect air-fuel ratio. If this is the case, your snowblower engine may be receiving too much air and not enough fuel because of the dirty carburetor.
  • You notice black smoke coming from the exhaust. This is a sign the engine is running rich, which means the dirty carburetor has caused the engine to receive too much fuel mixed with too little air.
  • If you have noticed an increase in fuel consumption this is another sign your carburetor probably needs cleaning.

If you notice any of the above, you may have a dirty carburetor, and it may be time to clean your snowblower carburetor.
