What Does a Carburetor Do?

Before we get to the nitty-gritty of cleaning your carburetor, it's important to understand how the carburetor fits into the scheme of your pressure washer.

For your gasoline-powered pressure washer to work, it needs the right amount of air to burn fuel properly. A normal air to fuel ratio is between 12:1 and 15:1. A mechanical gadget called a carburetor, which functions much like our heart, performs this balancing act. When your carburetor is clogged, it cannot pump the right mix of air and fuel.

Signs Your Carburetor Needs Cleaning

How do you know that a clogged carburetor is the problem? Just as some signs and symptoms help doctors identify your health issue, some signs and symptoms tell you that you may have a clogged carburetor. Among them are:

• It won't start.

A clogged carburetor can prevent air and fuel from passing through. Naturally, your pressure washer won't start. However, any malfunctioning part can result in this problem. So a dirty carburetor MAY be the cause but not necessarily the reason for a pressure washer to not start.

• It produces sneezing or popping sounds.

When there's an imbalance of fuel and air, you'll hear sickly sounds. This is because you're not getting enough fuel to the carburetor.

• It emits black smoke.

Now, if there's more fuel than air, then it results in your engine emitting black smoke from the exhaust.

• It leaks.

A block in the fuel bowl can prevent the needle valve from closing. Fuel then overflows into the carburetor.

What Causes a Clogged or Dirty Carburetor?

While it's important to know how to clean your carburetor, it's essential to learn what causes the problem and how to prevent it. After all, prevention is always better than cure.

To prevent build-up in your carburetor, you should avoid letting fuel sit in your pressure washer for an extended period. When some of the ingredients of the fuel evaporate, it leaves behind a thick, gummy residue. This sticky substance is what causes clogging and engine problems. A good cleaning is usually in order. In worse cases, you may need to rebuild or replace the whole carburetor.

Can you use WD 40 to clean a carburetor?

Another common question is if you can use WD 40 as well. You might be wondering what the difference between them are and how they compare.

Well, for starters, while both of these cleaning products offer a lot of benefits to your pressure washer, there are some differences in terms of their performance too.

For people who want an alternative that will do a similar job, they might be looking for something with more power and less residue.

However, if you're just looking to clean your carburetor without removing it, WD 40 will work well enough. It is also an option that's easy on the wallet which is always great so long as it works!

What can I use to clean a carburetor?

There are many different solutions that you can use to clean a carburetor. If you're working with an alcohol based cleaner, such as gasoline or acetone, then it is best to soak the carburetor in that for some time before reassembling and running the engine again.

You can also use a solvent-based cleaner such as CRC carburetor and choke cleaner. You should apply this to the interior of the carburetor with an aerosol spray and allow it to soak for about 20 minutes before running the engine again.

The best way is to remove your carburetor first, then clean it from inside out by spraying cleaner and scrubbing with a brush.

How to Clean Carburetor on Pressure Washer

To get your carburetor cleaned and your pressure washer running, here's our step-by-step guide. How to clean carburetor on craftsman pressure washer and other brands.

Pro tip: Remember to take pictures as you proceed so that you can reference later how the gears fit back into place.

Arrange also the pieces in the order that you took them apart. Lay them out on a towel on a flat surface to make reassembly no sweat.

Step 1: Remove the spark plug cap and turn off the fuel valve.

Step 2: Locate and access the carburetor. Normally, you may have to remove the throttle cover, air filter box, and intake setup to get to the carburetor.

Step 3: Find the gas line running between the fuel tank and the carburetor. Disconnect the tube from the carburetor nipple to empty old gas. If you have new gas in the tank, then you can clamp off the fuel line with your pliers first before pulling off the tube. In either case, place a bowl or a towel at the bottom to catch drips. Use WD-40 to facilitate easy removal of the rubber tube.

Step 4: Using a socket or nut driver, remove the carburetor from the engine by unscrewing the two bolts that connect it to the engine. Then, disengage the throttle cable from the carburetor linkage.

Step 5: Dump residual gas from the carburetor in a container or on a towel. Check if the carburetor is dirty or corroded. If it's corroded, then you need to buy a new one. If it's just dirty, then proceed with the cleaning process.

Step 6: Take apart the carburetor. Remove the carb bowl by unscrewing the bolt at the bottom. This will expose the float. Take out the pin that connects the float to the metal body. Then, pull off the needle valve. Take note of what material the tip of the needle valve is made of. If it's made of rubber, then don't use a carb cleaner with it. Remove also the rubber gasket on the rim where the mouth of the carb bowl seals into the main body.

Step 7: Spray carburetor cleaner on the nooks and crannies of the metal parts where you find crystals or gummy residues. If the material in the bowl or the metal part is liquid, then you can just wipe it dry. Remember not to use the carb cleaner on rubber parts! Inspect the main and idle jets as well to make sure these passages are clear. A small wire brush should help you clean them.

You can also soak the metal parts in a carburetor cleaner and leave it in for an hour.

Step 8: Next, rinse them in the water and blow dry with compressed air.

Step 9: As for the float and gaskets, wash with soap and water and let dry. If there are warped or torn gaskets, then replace them with new ones.

Step 10: Put back in the carb parts in their original positions—the needle valve, floater, pin, gaskets, and the carb bowl.

Step 11: Reconnect the carburetor to the main engine and return everything else in its original position. Refer to pictures you have taken if in doubt.

So there goes your step-by-step guide on how to clean the carburetor on a pressure washer. That should save you a trip to a repair technician and some bucks. And remember to empty your fuel tank every time you finish your pressure washing tasks to avoid those nasty build-ups from your fuel.

How do you clean a carburetor without removing it?

If you're interested in how to clean your carburetor without removing it, we'll talk about that next. In general, the process involves using some sort of cleaning product and then wipe off any remaining residue with paper towels or rags. However, before considering these options there are a few things to be aware of.

First, if you want to clean your carburetor without removing it from the engine, we recommend that you do not use a solvent-based cleaner because this may dissolve any gaskets or seals on the sides of your valve cover and in between various parts. If there are no valves or other fittings nearby then you should be able to use a solvent-based cleaner without any problems.

Second, when cleaning the carburetor without removing it from the engine you'll need some sort of device that's thin enough to fit into and around tight corners. Usually, this means using something like a toothbrush or other such shaped implement.

Third, if you're using WD-40 to clean the carburetor, be careful because this is a solvent and will dissolve any gaskets or seals on the sides of your valve cover.

As you can see there are several options for how to clean a carburetor without removing it from the engine. The first option we recommend would be using an appropriate solvent-based cleaner.

You'll need to do a little bit of preparation when using this option, but the upside is that you don't have to remove any fittings or valves in order to make it work.

The downside is that these cleaners are usually more expensive than some other options and they can be difficult to find depending on where you live.
