The carburetor, as we all know, is the heart of any automotive engine. It works by blending the air and fuel for an internal combustion engine.
Made up of lightweight alloy or aluminum, carburetors are common on small as well as large engines like cars, motorcycles, lawn-mowers, rototillers, ATVs, trucks, etc, for fuel injection purposes. When working, it burns the fuel to make the vehicle go forward.
However, as an engine’s carb works all through your way while you travel, it gets clogged with dirt, gunk, grease, and oil.
Cleaning a carb once in a while is hence important so that your vehicle’s engine runs smoothly and does not create any trouble down the road.
Also in a case when your motorcycle or car engine is not in use for quite a long time, the fuel in the tank and the carburetor start to break down. In this case, you may need to replace the fuel and clean your carb before you start your engine again.
Why Use Ultrasonic Cleaner for Carburetors?
The good thing about cleaning the automotive carburetor is it’s a simple and easy process.
Most of the time, it can be simply washed by soaking the carburetor in a carb cleaning solution for a few hours. After 1-3 hours, take it out and rinse properly with plain water. Dry it off, and it’s ready for use!
Although the manual cleaning process mentioned above is easy and fast, it is not very effective if your carburetor is too dirty.
Here comes high-tech devices such as ultrasonic carburetor cleaners, which make the process easier and more efficient.
Usually, the conventional manual cleaning technique only cleans the outer surface of the object. As it doesn’t reach the crevices and corners, it doesn’t clean the residue that is being accumulated within.
On the other hand, ultrasonic carb cleaning systems utilize high-frequency waves to efficiently remove several contaminants from the object immersed in the cleaning solvent.
The microscopic bubbles (created during the high-frequency cleaning process) then explode on the soiled surface of the carb to help remove the dirt, grime, and residue even from the most unreachable places. The results you get due to this cavitation process are amazing and beyond belief, especially concerning complex carburetors.
Not only does it reduce the overall time and money spent on cleaning a carburetor, but it also helps to deliver the best results that have never been attained with any other cleaning agents.

What Size Ultrasonic Cleaner to Get for Carbs?
With the best range of ultrasonic carb cleaner machines for car and motorcycle carbs mentioned above, you can hopefully find the best one as per your requirement.
Often people make a mistake in judging the right carb size and the right cleaner they need. Hence make sure that you choose the RIGHT SIZE digital cleaner with an appropriate size cleaning tank that easily fits your carbs.
It is best to measure the overall dimension of your carburetor (including carb parts such as float bowls, slides, jets, etc.) that need to be cleaned before you order your machine online.
You can get a rough estimate of the size without removing the carb from the car engine or bike.
Then get a machine that is good enough to accommodate the whole of it.
- In most cases, a machine with a 3-liter tank is sufficient if you want to clean a small Honda motorbike carb one at a time.
- However, if you need to clean bigger carbs (like a car, lawn-mower, ATV, or other utility vehicles), it’s good to get a unit with a six or 9-liter tank.
- If you need to clean a batch of a few carbs (smaller as well as larger ones) in one round, it’s good to buy a commercial-grade machine that comes with a 20L tank
Although you can get the machine exchanged, it can be a hassle that should not be worth taking!
The key to getting the right size cleaning machine for your two-wheeler or four-wheeler carb is to order a bit bigger size machine than your measurement.
Of course, it will cost you a bit more, but it will save you from all the hassles involved in returning the machine, just in case you get the wrong size.
When choosing a cleaning machine, you may require to look at a few other factors besides the right size.
Some of these include:
- Rugged stainless steel tank
- Power and frequency of the unit
- Timer cycle, digital display, auto shut off
- Ability to heat the solution via a built-in heater
- Warranty and customer service from the manufacturer
Before picking one and using the device, do not forget to read the instructions & other details carefully.
What Parts of the Carb Can I Clean in the Machine?
Usually, all the parts included in the carb get worn out over time; practically, the more you run your vehicle (motorcycle, car, or any other), the more it gets grimed.
The parts that most often wear or deteriorate are the Carb-O-Rings, Needles, Diaphragm Rubbers, Slide Carrier, Float Valve Tips, Springs, Jets (like Main Jet, Pilot Jet, Needle Jet), and the rubber intake.
Although most of the parts in this mechanical device are moving, a few parts don’t move and deteriorate with age.
It is therefore essential that you clean the parts regularly for better upkeep and performance.
By using an automatic machine like an ultrasonic carb cleaner, you are making things pretty much easier when it comes to cleaning all the smudged carburetor parts.
You only need to place your carb in the machine and without you knowing, it can clean the outer surface as well as all the inner parts of the carb that are tough to clean manually.
When and How Often Should You Clean a Carburetor?
The answer to this question will depend on your driving style, how far you drive, the quality of fuel you use, and much more.
Most of the workshop mechanics out there recommend using a spray cleaner every month for regular carb cleaning.
While a full carburetor cleaning at a professional level (using an ultrasonic carb cleaner machine) can be done every 3-4 months.
You’re driving time and distance matter much when it comes to deep cleaning your motorcycle carbs. Because the more you drive, the more your carbs need to work to reach your destination.
And in a way to reach your destination, it’s more likely that you will fill up your vehicle’s tank with a range of fuels that come from different brands (which can be a mix of low and high quality).
For this reason, many mechanics suggest the most appropriate time for cleaning your gunked aluminum carburetor to be between 20- 30,000km.
How Do You Know If Your Carburetor Needs Cleaning?
If you are not sure whether its time to clean your carb, you should check for the following signs in your engine:
- The engine does not start or take too much time to start
- It’s running lean and causing a popping sound may be due to a bad fuel supply
- It’s running rich due to excess fuel, and less air may cause black smoke from the exhaust
- It’s flooded or overflows, causing it to flow out of bowl vents and wet spark plugs
In most cases, a carburetor is not the one that is causing the real problems. However, in many cases, when left dirty, it caused severe issues while still showing these signs.
How to Choose the Best Ultrasonic Cleaner Solution for Carburetors?
Although plain heated water with a bit of detergent can do the job for you, getting a specialized cleaning solvent that is meant mainly for cleaning the carbs can do much better.
If you want, you can also use a homemade ultrasonic cleaner solution for carburetors which can be made at home with a few easy steps.
However, care that these DIY homebrew solutions are not much effective and cannot be replaced with professional-grade cleaner solutions available on the market.
Using a high-quality ultrasonic carburetor cleaning solvent is thus recommended, which can easily knock off all the petrol and grease deposits in very little time, thus saving you time and money!
Tips for Using The Ultrasonic Carburetor Cleaner Solution Safely
When using the cleaning fluids in your ultrasonic cleaning bath, make sure that you use them properly with utmost care.
- The solvent that may rise to the bath’s surface should be skimmed off and disposed of.
- When the solution takes much longer to clean the surface or if found discolored, replace it with a fresh one.
- When replacing the old cleaning liquid, take care that you drain and dispose of the fluid according to your local regulations.
Ultrasonic carb cleaning solutions deliver a wonderful performance when used with utmost care and precautions.
Just in case you do not want to use an ultrasonic carb cleaner machine, solutions such as Simple Green, Pine-Sol, Lacquer thinner, Seafoam, and many others can also do a job alone. These solutions can also be used in automatic ultrasonic cleaning devices if you want, making the process much easier, faster, and more efficient.
How to Remove and Clean a Carburetor with Carb Cleaner? (Without Sonic Machine)
The carburetor maintains the amount of air and fuel entering the cylinders; hence, it needs to be kept in good shape for efficient bike performance.
However, if you haven’t worked on a carburetor before, then it may be slightly daunting for you.
Worry not, here is a guide to help you clean your motorcycle carburetor. Make sure you wear safety gloves and keep all the lights on.
Step 1: Remove the carburetor
Switch off the main fuel supply and drain the float chamber. Disconnect the control cable and slide after the carburetor is removed.
Now remove the float chamber. Turn the carburetor upside down and remove the screws one by one.
Step 2: Remove the floats
After you have removed the float chamber, you can see the main jets, primary jet, and overflow pipe. Make sure the floats are not leaking.
Make sure you check it after removal. Take great care in removing the pin as the aluminum stand which holds it is susceptible to damage and breaking.
Step 3: Remove and Clean Jets
A lot of bike carburetors use a two-jet system. The primary jet handles fuel flow from idle to 1/3rd throttle, and the major jet controls fuel of the remaining 2/3rd.
Sometimes the primary jet gets blocked. To fix it, you need to clean the jet or replace it.
Step 4: Air Adjusting Screw
Another thing that should be removed from the carburetor body is air. The tapered screw impacts the mixture strength and combines with the primary jet.
You can set the screw at a number of turns, and it needs to be put back to this position while reassembling.
Step 5: Cleansing
Once all the parts from the carburetor body have been removed, you should clean and evaluate them.
Every hold in the carburetor should be cleaned by using a high-quality carb cleaner spray and then blown through compressed air.
If you do not have a carb cleaner available, you can also use substitutes such as Brake Cleaner, Simple Green Pro HD Heavy-Duty Cleaner, or simply a Kerosene (or paint thinner) that’s available at your home or garage.
Make sure you also coat all the parts with WD40 well before reassembling them for better protection and functioning.
Step 6: Reassembling the carb
Now, make sure you reassemble everything in the right way. Re-attach the carburetor to the wires and keep them back in their places.
Once the carburetor is overhauled, you should fine-tune the air adjusting screw. Make sure the engine gets to normal temperature after the carburetor has been reattached.
Wrapping up
A healthy heart is a sign of good health. And the same is true for your bike engine. Except its “heart” is a “carburetor.” Like excess cholesterol in your heart can affect its functioning, the dirt and fuel residue, if it gets accumulated in a carburetor, can hinder the performance or completely block your vehicle.
Regular maintenance and cleaning will ensure that your bike runs smoothly while maintaining its top performance.
Problems with your vehicle’s carburetor are often due to its parts becoming dirty. Also, if there is excess fuel flow, the carburetor in the engine can flood, causing the vehicle to run poorly, have bad fuel economy, or become smoky when running. In any case, you need to get the carb inspected, cleaned, and fixed by a professional.
For average users and under normal conditions, the carburetor on a bike should run for roughly 50,000 km without any fuss and without needing replacement. However, if you see signs of damage soon that do not get repaired by cleaning, it’s time to replace it.
