What is a Good Quality Carburetor Cleaner For Lawn Mower: Buying Guide

The greatest enemy of the carburetor is the downtime of machines; on the one hand, rust can set in here, but on the other hand, deposits can also arise from evaporated fuel. Different types of soiling, require different types of cleaning.

In the case of cleaning a lawn mower carburetor, you should generally refrain from so-called household remedies, incorrectly cleaned could lead to a complete defect in the worst-case. On the one hand, this would be annoying, but it would also be quite costly and time-consuming in the worst case.

A thorough evaluation of the cleaning products is, therefore, all the more critical.

  • What kind of contamination is there?
  • Are there products that have been testing winners for a particularly long time?

How Often Does The Cleaning Need To Be Repeated

While a liquid carburetor may be sufficient for minor contamination to achieve a satisfactory result, an ultrasonic bath must be used for stubborn and large-scale contamination. Unfortunately, this cleaning form is a lot more complicated, time-consuming, and certainly not for those who have little or no idea about engines and carburetors.

But even with the liquid application, a distinction is again made between spray, which can be used to clean smaller areas. The cleaner is also available as a solution, where cleaning takes place by adding to the fuel.

These products reviewed by us for a long time have already been thoroughly tested. The more effectively a carburetor cleaner works, the less often the cleaning process has to be repeated, and some cleaners also have a preventive and protective effect against renewed contamination. In general, however, you should pump the fuel out of the tank to avert evaporation for a long time and deposits cannot even form in the carburetor.

Carburetor Cleaner (According To Customer Rating)

Customer ratings can also prove useful. Since we do not want to give any firm recommendations here, other consumers’ reviews can reinforce the decision that has already been made or even induce them to reconsider them. It would help if you never trusted such customer ratings alone because everyone has a different view of things, and opinions can differ significantly. In the end, only a self-performed test provides absolute clarity.

Carburetor Cleaner (by Price)

If you cannot decide on a product despite all the recommended criteria, the price should be included in the selection. However, that does not mean that you have to take the most expensive product on the list to get high quality. On the contrary, the cheaper variant can also achieve effective cleaning and thus be a suitable alternative.

Application & Effect

The effect of the various carburetor cleaners is, in all liquid cases, a dissolving effect due to the different carbons in the mixture. The spray available on the market is particularly suitable for small areas; in some lawnmowers, the spray can be sprayed directly onto the dirt, and then the deposits can be rubbed off with a cloth.

The product that gets into the carburetor via the fuel also has a protective component, which ensures that new deposits have no chance at all. This type of lawn mower carburetor cleaner is necessary for a fresh tank filling of at least 75%.

On the other hand, the ultrasonic bath achieves cleaning in which the pressure waves burst the deposits open and thus detach them from the surface. This type of cleaning is particularly effective as it works right into the smallest corner, but the carburetor must first be removed. If you have no idea about it, you better leave the cleaning to a professional!

How To Clean a Lawn Mower Carburetor

Repeatedly pulling the manual starter of the mower can cause annoying engine sputtering. Or maybe the engine starts, seems to run, and then stops. Your mower will interfere with your mowing plans for the first time this season. This lack of cooperation often indicates dirt on the carburetor.

Carburetors mix air and gasoline in the right amounts to create a fuel mixture. They are also an excellent combination for engine starting and engine speed control. When you clean the carburetor on a lawnmower, you cut before you know it, and this should be part of regular maintenance.

Put the mower on a flat surface and disconnect the fuel line. Locate the nut under the bottom of the carburetor and twist it to remove it. Please leave it in a safe place in case you need to reinstall it. When removing the carburetor’s bottom, there may be a fuel leak, so a newspaper needs to be placed underneath to soak it.

Spray the carb cleaner on the bottom cup of the carb, including the plastic needle valve. Clean all sticky substances and deposits. If you leave gasoline in your cutter in the winter, it will turn into paint that clogs the inside of the carburetor. Removing all broken gasoline, debris, and dust will help to start the engine faster.

Spray the cleaner on the rest of the carburetor. Wipe them clean, removing all paint and sticky substances. Check that all the holes are clean and clean the sealed brass rubbers with a wire. Some people find it easier to do this job with compressed air.

Reassemble the carburetor and make sure each part is correctly positioned and the bolts are tight. Complete the assembly by replacing the nut on the bottom of the carburetor.

Reconnect the fuel line, prime the engine, and pull tight by hand. The cutter should start working immediately. Otherwise, the fuel line may be blocked, or the air/fuel mixture may be incorrect.

Locate the carburetor air control valve. Turn it clockwise as far as it will go, then counterclockwise twice. This valve helps control the fuel/air mixture. Try pulling the starter again to check that the engine is starting. Turn the valve a little bit to the left for the engine to work correctly.
