A pressure washer is a piece of equipment used to clean and strip away the top layers of the surface. They come in all different shapes and sizes and can be used for a variety of purposes.
A carburetor is an essential part of a pressure washer. The pressure of the fuel is regulated by the choke and the throttle.
However, over time, residue such as dirt and grime buildup in the carburetor. This blog will explain how to clean carburetor on pressure washer and the benefits of doing so.
What Does Carburetors Do?
Carburetors are found on many different types of engines, which is why it’s important to take a few moments to familiarize yourself with them before you begin operating a pressure washer.
Once you know their functionality, you’ll be able to maintain and care for yours much more effectively. Simply put, the carburetor works like a saloon’s bartender. He mixes up drinks (fuel) for your car (pressure washer) ensuring that its tank has the proper mixture of air and fuel; otherwise, the system simply will not function properly.
The ratio should be around 12:1 to 15:1 – anything outside that range could cause your unit to malfunction. Sometimes a carburetor in a pressure washer can get gummed up with dirt and grime which in turn leads to the engine running too rich or too lean.
This might occur because there isn’t enough fuel going into the combustion chamber or because there is too much.
The main point here is that without enough air and fuel getting where they need to be, your pressure washer will not perform at an optimal level and might even stall out.
So, it follows that without a properly functioning carburetor your pressure washer will not work properly.
Signs that a Carburetor Needs Cleaning
If your carburetor needs to be cleaned, it will generally let you know when this happens (although there are circumstances when you may fill up with petrol and not notice until it’s too late).
It is worth looking into the inside of your carburetor if you think there is a problem.
Failure on Startup
If your pressure washer is having difficulty starting, then there’s a good chance that the carburetor might need some attention.
You could always check into putting gas into the fuel tank first, but before you do anything else it’s worth checking if your fuel line is clogged or filled with air, for example.
Sometimes simple problems like this will keep things from starting up properly.
Popping and Sneezing Sounds
If you smell any pops and sneezes coming from your carburetor, it’s the worst sign it could be telling you about.
It typically happens when there is an imbalance between the amount of fuel and air mixing.
If there isn’t sufficient fuel mixed into the air then you might notice a popping sound coming from the carburetor itself.
Black Smoke
If black smoke is coming out of your pressure washer, then there’s a good chance that something in the carburetor isn’t working correctly.
Excessive fuel flow could mean the fuel isn’t being distributed properly and it will lead to the carburetor increasing pressure until it builds up enough force to create a huge amount of pressure through the discharge pipe. This will make everything work too hard until they get stuck and you get a big leak.
Leaks
When a carburetor is clogged, fuel can’t pass through to be converted into combustion. If the fuel isn’t being accessed, then it will cause leaks out of your pressure washer’s carburetor.
If you pay attention, you might notice that if there are any leaks from the carburetor, there is a potential problem with the flow of fuel to your pressure washer and ultimately this could create a major leak!
So make sure you keep the carburetor clean because clogs can easily happen after time from constant use or debris from various projects around your home or business.
What Causes a Clogged or Dirty Carburetor?
Avoid letting fuel sit in your pressure washer for an extended period of time. Some of the ingredients will evaporate and leave behind a residue which can clog your carburetor and create engine problems.
If you notice that the pressure washer is not operating at 100%, it may be time to rebuild or replace the engine.
There are ways to avoid this situation from happening; for example, you need to make sure there is a fuel mixture as well as proper oil levels within the engine.
You should also clean your pressure washer on a regular basis – depending on how hard you use it – and check regularly if any part of its parts, such as filters, hoses, and connectors, appear to be defective or damaged in some way.
Cleaning of Pressure Washer’s Carburetor
Learning how to clean your pressure washer’s carburetor can be an exhausting task, especially if you’re not familiar with it.
If you want to complete the job successfully – and remember how to do it next time around – try taking pictures of all the parts before you dismantle your machine.
This way, you will avoid forgetting where exactly everything goes after putting everything back together.
Putting pressure washers back together is a skill that most people take time to acquire, so don’t feel bad if this isn’t something you feel confident doing.
You could do yourself a favor by laying the parts out on the ground as opposed to dropping them straight back in as this can damage them and make it difficult to reassemble your pressure washer correctly.
Steps to Clean Carburetor
Turn the Fuel Valve Off
First, turn off the main fuel line and remove the gas cap from your carburetor. This ensures that fuel won’t accidentally leak out while you’re cleaning. Here’s more on how to clean a carburetor.
Access the Carburetor
Next, find the carburetor. Then proceed to find and access the carburetor on the side of the engine block. After that, you’re going to need to disconnect a series of intake tubes and cover plates in order to get your hands on it.
You might not be able to get rid of or avoid hitting gas while doing this; make sure not to spill any excess fuel before you take the cover off completely.
Empty the Gas Tank
Before cleaning the carburetor, find the fuel line that is connecting the carburetor and the fuel tank. If one were to empty out the gas, they would remove the tube that is connected to the nipple of the carburetor.
One may also leave the gas if they have fuel – in which case, they should just clamp off (or cap) the fuel line.
Regardless of which method you choose, your goal is simply to catch any stray drips by placing a towel or bowl at the bottom during this procedure.
Remove the Carburetor
In case you needed a little more guidance, your model’s factory-installed nut driver should be similar in appearance.
First, unscrew the nuts from both ends of your carburetor by using the matching sockets from within your pressure washer’s tool kit.
If you look closely at the engine model which is beside your power tool’s handle, you will notice that grips above it help to give a better grip when holding a nut driver.
Next, disconnect your machine’s throttle cable from its existing linkage by turning it counterclockwise with a simple twisting motion.
Remove Residual Gas
To start cleaning your moped, first, you will need to remove any gas that may have spilled during the time that it was out of use.
You can do this by carefully putting a towel into the gas tank or simply allowing some floor cleaner to soak into the moped’s interior.
After you’ve done so, check whether any parts within the engine are corroded or damaged and/or if there is rust around the moped’s handlebars or steering wheel. If so, contact a professional. If not, proceed with cleaning.
Take the Carburetor Apart
Alright, it’s time to take another picture, and this time we want you to show how the carburetor is connected.
First, start by unscrewing the bottom pump assembly in order to remove the disc piece. This bit will be used with almost any type of pressure washer, whether it’s a residential or professional one.
Next, you can disassemble each bit that makes up the carburetor assembly if possible. One last thing, make sure to snap a picture of how it all goes back together.
Spray the Carburetor Cleaner
Now that the bulk of dirt has been removed, you can spray your carburetor cleaner onto the parts that require cleaning. Be sure to avoid spraying any part made of rubber as this would damage it if the cleaner was applied (cleaner is too harsh).
Regular soap and water should be sufficient for cleaning these parts. Rinse every piece properly and let them dry.
Reconnect
After you clean your carburetor, arrange the bits and pieces back in the order they came out. Use the pictures you took before as a reference.
