The lingering question for many snowblower owners surrounds knowing when a carburettor needs cleaning. Here are the telltale signs –

1. Starting Problems

If your carburettor is clean (and working smoothly), the snowblower engine should start without much ado. Carburettors fail to start correctly when grimy because the dirt blocks the correct combination of fuel and air from travelling through their usual opening to the engine, bringing all manner of problems.

2. Poor Idling

If you notice that it suddenly develops a habit of rough idling (your blower feeling irregular and bouncy when its engine is running) or it’s idling too fast, then it could be time to cleanse it.

3. Uneven Acceleration

Again if it’s working properly, it should accelerate without stumbling. So unbalanced or start-stop acceleration is another clear sign that you need to clear any deposits.

4. Greedy Fuel Consumption

When it develops an increased appetite for gas, then it could be that it’s dirty.

5. Flooding

They are flooding results when too much fuel gets into the cylinders. A carburettor could be faulty or have debris in its needle valve, making it stick open, causing a spillage. What To Do Before choosing the right snowblower carburettor cleaner? To effectively remove gum, varnish, and dirt from the carburettor, you will need to do some preliminaries.

6. Revisit Your Owner’s Manual

To have it your way, it’s better first to go back to your snowblower’s owner’s manual. Your motive will be to re-read everything about the carburettor. You will most likely come across rich information that may help you during the process. You can download the manual from the manufacturer’s website if you no longer have a copy.

7. Check The Condition Of The Air Filter

Start by inspecting your air filter condition to ensure that only clean air (free of residuals) comes into your carburettor. That’s because your snowblower will continue emitting black smoke even after cleaning if the air filter is clogged. Clean the filter or replace it if it’s nearing the end of its useful life.

Cleaning Your Snowblower’s Carburetor Without Removing It – Step By Step

You will use a cleaner to cleanse the carburettor while it’s still in the snowblower. Carburettor cleaners are liquid solutions made to methodically dissolve layers of dirt and choke from the inside/outside of the carb to improve engine performance and reduce downtime.

Items You Need:

Step 1: Turn Off Your SnowBlower

Maintaining a machine when it’s running can be hazardous. So start by turning off your snowblower. Also, allow it a couple of minutes to cool off.

Step 2: Remove The Muffler

To fully access the carburettor, you have to remove the muffler. Using your socket wrench, remove the bolts/nuts holding the snowblower’s muffler in place. The manual should help you locate the damper on your engine assembly.

Step 3: Take Out The Gas Tank

Here you have to be mindful not to spill fuel. Still using your socket wrench, remove the bolts holding the snowblower’s gas tank. Then slide it carefully off and place it aside.

Step 4: Place an Empty Pan/Container Under the Bowl

You will be draining fuel from the carburettor in the next stage, and to do this, you require a collecting container. So, site your snowblower’s carburettor bowl – check your manual- and place a container or pan under it.

Step 5: Drain The Fuel

It’s almost impossible to unclutter your carburettor without emptying fuel effectively. To do this, remove the nuts on the base of the bowl. Fuel will start draining from the carburettor. Wait until your carb is fully emptied before removing the pan.

Step 6: Clean The Bowl

By now, your carburettor’s bowl is loose. Twist it off. Now wet a piece of clothing with your carburettor cleaning solution. You can now clean the bowls inside.

Step 7: Scrub The Nuts

Some residue remains typically on the nuts. To remove such debris, spray a sufficient amount of your cleaning solution on the bowl’s nuts and scrub them using a wire brush.

Step 8: Clean Dirty Holes

Using a copper wire, clean out any visibly tarnished small holes in your carburettor. Also, spray around the carburettor’s throat to eliminate deposits from its throttle plate area.

Step 9: Blow Leftovers

Wipeout any other grim that may be pending by blowing it out using compressed air. For maximum efficiency, apply the compressed air can to each hole.

Step 10: Reassembly

Now all the grim should be out in the cold and your carburettor spotless. Reassemble the carburettor bowl and everything else by following the previous steps in reverse. Don’t forget to shine the outside of your carburettor plus all other linkages once you put back everything into place.


  • The engine should be off and cool.
  • Never spray on electrical connections.
  • Some of the sprays deface painted surfaces. In case you accidentally spray on such painted areas, wipe it off at once to avoid damage.

Wrapping It Up

Knowing how to clean a snowblower carburettor without removing it saves you time and the stress of opening a carb. And the best part is that it’s as effective as the traditional carburettor removal approach. You will no longer experience hard starts, sputtering, bouncy idling, and all the related teething problems. So, don’t let carburettor problems suffocate your snowblower just because you aren’t a fan of opening stuff. Experiment with our steps, and over time, you should become a pro.
