How to Clean a Snowblower Carburetor Without Removing It

A snowblower carburetor is a tool for clearing snow from undesired areas, like streets, driveways, and train tracks. It uses auger spins to propel snow into the outlet, and the snow is flung to the side by the discharge chute. The snowblower’s carburetor, a unique piece of engineering, is the machine’s unsung hero. It has an original layout and can serve its purpose for quite some time, provided it is cared for appropriately. 

For the carburetor to function at its fullest, you need to clean it regularly and remove anything that may affect its performance. Below are steps on cleaning a snowblower carburetor without removing it. 

How to Prepare Your Carburetor for Cleaning

Preparation is key to successfully cleaning the carburetor of varnish, gum, and grime. The two things you need to do before cleaning the carburetor are as follows:

Review the Instruction Manual 

Referring to the instructions that came with your snow blower will help you get the desired results. It’s recommended that you review all carburetor-related material. You never know what you’ll find while cleaning that could be crucial later. Download the user guide from the manufacturer’s website if you’ve misplaced your old one. 

Assess the Filter’s Condition 

It is essential to check the quality of the air filter to guarantee that the carburetor receives clean air. Even after cleaning, the snowblower will continue to give off black smoke if the air filter is clogged. It’s a crucial consideration before you clean the carburetor on your snow thrower. 

Steps in Cleaning the Snowblower Carburetor Without Removing It

While still installed on the snow thrower, the carburetor will be cleaned with a unique cleaning solution. Carburetor cleansers are liquid solutions designed to remove built-up dirt and gunk from the inside and outside of the carb to restore optimal engine efficiency and save downtime. 

What You’ll Need:

  • Carburetor cleaning solution
  • Compressed air can
  • Copper wire
  • Socket wrench
  • Wire brush

Step #1 Turn Off the Snowblower

Before doing any work, please make sure the fan is turned off. To avoid injury, wait for the blower to calm down for a time. 

Step #2 Take the Bowl Off the Carburetor

Once the carburetor has been located, the fuel jet must be disconnected so that the carburetor bowl may be removed. Suppose this is your first time doing so. In that case, it is recommended that you consult the owner’s manual for your snowblower’s carburetor to familiarize yourself with the location of the various components. The inside of the bowl is now covered with dirt, liquid, or concentrated fuel. You need cleaning materials like a rag and some carburetor cleaner. 

Step #3 Clean the Carburetor Fuel Jet and Bowl

Cleaning the bowl is as simple as spraying on some carb cleaner and wiping away the dirt and residue. You need to make sure it’s free of debris before you can go on to the fuel jet. It’s time to grab the gasoline jet again and try again. 

The holes can be cleaned by spraying a carb cleaner and scrubbing them with copper wire. Using copper wire, avoid damaging the brass surface and destroying the jet’s accuracy holes. Perform one last test spray to ensure the liquid is expelled from each tiny opening. Because of this, we know the jet is no longer obstructed. 

Step #4 Check the Emulsion Tube Now

Remove the fuel jet and carburetor bowl and set them aside for now. For this, there are three main concerns you should have in mind. You need an emulsion tube, a bowl of water, and a needle. Quickly spray the emulsion tube with the carb cleaning. One example is a floating bowl secured around the emulsion tube by a sliding needle. If the floating bowl starts to stick, you’ll need a new one. Take out the movable needle and disconnect the airborne dish. It has a needle that is always pointed inward. Disassemble the system, clean up the mess, and then reassemble it. 

Step #5 Adjusting the Carburetor Bowl

Reconnect the carburetor to the fuel jet and fine-tune the setup above the emulsion tube. You can’t effectively tune the system or seal it off until you first ensure the rubber gas kit is installed on the machine.
