You occasionally have to clean a dirty snowblower carburetor to avoid facing an impeded performance.
And while you can remove it and scrub the carburetor from outside the blower, knowing how to clean a snowblower carburetor without removing it saves you a lot of time and stress – especially if you passionately dislike opening up machines.
The good thing is that you don’t have to be a rocket scientist to hack it- as you will see shortly.
But before we look at that,let’s briefly look at a few issues related to a snowblower’s carburetor:
The lingering question for many snowblower owners surrounds knowing when a carburetor needs cleaning.
Here are the tell tale signs.
If your carburetor is clean (and working smoothly), the snowblower engine should start without much ado.
Carburetors fail to start properly when grimy because the dirt blocks the correct combination of fuel and air from traveling through their usual opening to the engine, bringing all manner of problems.
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.
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.
When it develops an increased appetite for gas, then it could be that it’s dirty.
Obviously flooding results when too much fuel gets into the cylinders.
A carburetor could be faulty or it may have debris in its needle valve -which makes it stick open causing a spillage.
To effectively remove gum, varnish, and dirt from the carburetor, you will need to do some preliminaries.
To have it your way, it’s better to first go back to your snowblower's owner's manual.
Your motive will be to re-read everything about the carburetor. 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.
Start by inspecting the condition of your air filter so as to ensure that only clean air (free of residuals) is coming into your carburetor.
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.
You will use a cleaner to cleanse the carburetor while it’s still in the snowblower.
Carburetor cleaners are liquid solutions made to methodically dissolve layers of dirt and choke from the inside/outside of a carbso to improve engine performance and reduce downtime
Maintaining a machine when its running can be hazardous.
So start by turning off your snowblower.
Also, allow it a couple of minutes to cool off.
To fully access the carburetor, 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 muffler on your engine assembly.
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.
You will be draining fuel from the carburetor in the next stage and to do this, you require a collecting container.
So, site your snowblower's carburetor bowl – check your manual- and place a container or apan under it.
It’s almost impossible to effectively unclutter your carburetor without emptying fuel.
To do this, remove the nuts on the base of the bowl. Fuel will start draining from the carburetor.
Wait until your carb is fully emptied before removing the pan.
By now, your carburetor’s bowl is loose.
Twist it off.
Now wet a piece of cloth using your carburetor cleaning solution.
You can now clean the bowl’s inside.
Some residue normally remains 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.
Using a copper wire, clean out any visibly tarnished small holes in your carburetor.
Also,spray around the carburetor’s throat to eliminate deposits from its throttle plate area
Wipe out any other grim that maybe pending by blowing it out using compressed air.
For maximum efficiency, apply the compressed air can to each hole.
Now all the grim should be out in the cold and your carburetor spotless.
Reassemble the carburetor bowl and everything else by following the previous steps in reverse.
Don’t forget to shine the outside of your carburetor plus all other linkages once you put back everything into place.
Wrapping it up
Knowing how to clean a snowblower carburetor without removing it saves you time and the stress associated with opening a carb.
And the best part is that it’s as effective as the traditional carburetor removal approach.
You will no longer experience hard starts, sputtering, bouncy idling and all the related teething problems.
So, don’t let carburetor problems to 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.
