How to clean snow blower carburetor? A clean snowblower carburetor is the key to keeping your machine running smoothly during winter. If you’re a snow blower owner, you know that your trusty machine becomes your best friend when the snow starts falling. But just like any good friendship, it requires some maintenance to keep it performing at its best.
The main problem
A dirty carburetor is one of the most common issues that can plague a snowblower. When this crucial component becomes clogged, it can lead to a host of problems, including difficulty starting your blower, poor fuel mileage, and even snow blower engine damage.
Understanding the snow blower carburetor
To understand the importance of cleaning your snowblower carburetor, let’s first delve into what this vital part does.
It plays a central role in your snow blower’s engine.
It’s responsible for mixing air and fuel in the right proportions, ensuring the engine runs smoothly and efficiently. When it works correctly, your snowblower starts effortlessly and delivers the power needed to clear snow effectively.
How does the snowblower carburetor work?
The carburetor’s primary job is to atomize the fuel into tiny particles and combine them with the right amount of air, creating a highly combustible mixture.
This mixture is then sent to the engine’s internal combustion chamber, where it’s ignited by the spark plug, resulting in the power needed to turn the snow blower’s auger and throw snow out of the chute.
The small internal combustion engines rely on a carburetor to precisely control this mixture.
Signs of a clogged carburetor
It’s crucial to recognize the signs of a clogged carburetor. Identifying these symptoms early can save you from more significant issues down the road. Here are some telltale signs that your snowblower carburetor may need attention:
Difficulty starting: if your blower is struggling to start or requires numerous attempts before it starts, it’s a clear indication that the carburetor may be clogged.
Poor fuel consumption: a clogged carburetor can lead to inefficient fuel consumption. You may find that your snow blower is guzzling gas faster than usual, causing you to refill the tank more frequently.
Loss of power: when the snowblower carburetor fails to deliver the proper air and fuel mixture, your blower may experience a noticeable loss of power. It might struggle to throw snow effectively or bog down when faced with heavy snowfall.
Stalling or surging: if your snowblower engine is stalling or surging – suddenly speeding up and slowing down without your input — it’s a clear sign of carburetor trouble.
Smoke and emissions: a clogged carburetor can lead to excessive smoke emissions from your snow blower’s exhaust. If you notice black or smoky emissions, it’s a signal that a snowblower carburetor is throwing too much fuel mixed with too little air into the engine, or that it is not getting any clean air due to dirty air filters.
Preparation for cleaning
Cleaning your snow blower’s carburetor is a task that requires careful preparation and adherence to safety measures.
While it is possible to clean a snowblower carburetor without removing it from the blower, it is better to completely disassemble the snowblower and clean it thoroughly.
Before diving into the process, let’s go over the essential steps you need to take to ensure a successful and safe cleaning session.
Revisit the manual
If you want to clean a snowblower carburetor your first step should be to re-read the manual. If has all the necessary information you that can help you clean your blower.
Safety always comes first! Begin by disconnecting the plug wire from the spark plug. This step is crucial to prevent any accidental starts while you’re working on the carburetor.
Work in a well-ventilated area. Carburetor cleaning involves the use of chemicals, such as a carb cleaner, which can produce fumes. Ensure you’re working in a well-ventilated area or even outdoors to avoid inhaling these fumes.
Gather the necessary tools and materials
Carburetor cleaner: you’ll need a quality carb cleaner to clean the carburetor components effectively. Look for a snow blower carburetor cleaner that is specifically designed for small engines like those found in snow blowers.
Compressed air: compressed air is an excellent tool for blowing away debris and dirt from hard-to-reach areas, like the snowblower air filter. It’s essential for achieving a thorough clean, especially when dealing with a clogged carburetor.
Cleaning solution: you also require a cleaning solution to soak and dissolve stubborn deposits within the carburetor. This is particularly useful for cleaning parts like the emulsion tube and the needle valve.
It’s time to roll up your sleeves and get to the heart of the matter: cleaning your snow blower’s carburetor.
We’ll break down the process into manageable steps, ensuring that we address each phrase and its significance in maintaining your snow blower’s peak performance.
Removing the carburetor bowl
The first step in the cleaning process is removing the carburetor bowl. This bowl is where fuel accumulates before being mixed with air. To access it:
- Locate the snowblower carburetor. It’s typically situated near the engine and has a bowl-shaped component beneath it.
- Carefully disconnect any linkage or cables attached to it.
- Remove the bolts securing the carburetor bowl in place using a wrench or socket set.
- Gently lower the carburetor bowl, draining any remaining fuel inside into a container.
Once you have removed the carburetor, give it a thorough soak in the cleaning liquid. This will help remove the general impurities.
After three hours remove the carburetor from its bath and rinse it with clean water. Now it’s time to clean all the components thoroughly.
Using carburetor cleaners
Snowblower carburetor cleaner is your best friend when it comes to effectively cleaning the inner workings of the carburetor.
Spray the carb cleaner generously on all visible components, including the fuel jet, emulsion tube, and needle valve.
Cleaning the fuel jet and emulsion tube
The fuel jet and emulsion tube are critical in regulating the air-fuel mixture. Use a carburetor cleaner with a narrow nozzle to ensure you reach and clean these parts thoroughly.
Using a copper wire for thorough cleaning
Sometimes, deposits can be stubborn and require a bit of extra effort. Use a piece of copper wire to gently clean out any clogged holes or residues.
Addressing the needle valve and rubber gas kit
Inspect the needle valve for any wear or damage. If necessary, replace it along with the rubber gas kit to ensure a proper seal.
Blowing the air filter
While you’re at it, don’t forget to blow the air filter with compressed air. To clean air filter use hot water and dish soap, as carb cleaner might damage it. This guarantees that the carburetor receives a supply of clean air.
Cleaning the throttle valve
The throttle valve controls the flow of air into the carburetor. Ensure it’s clean and free of debris to maintain precise control of your snow blower’s engine.
Putting it back together
Finally, once all the components are clean and in good condition, it’s time to reassemble the carburetor.
Put all the parts back together in reverse order of disassembly.
Testing and adjustments
With the carburetor cleaned and reassembled, it’s time to put it to the test and make any necessary adjustments to ensure your snowblower runs smoothly. Turn the engine on and let it run for a couple of minutes.
Can you clean a snowblower carburetor without removing it?
Yes, you can clean a snowblower carburetor without removing it in some cases. This method is often referred to as a “partial cleaning”. To do this, follow these steps:
1. Locate the carburetor and the air filter housing on your blower.
2. Remove the air filter cover and air filter.
3. Spray carburetor cleaner directly into the carburetor throat while the engine is running. This can help dissolve some of the deposits and clean the carburetor to a certain extent.
However, please note that cleaning the snowblower carburetor without removing it may not provide as thorough a cleaning as removing and disassembling it.
