This is the best way to clean a carburetor!

[Display]

The carburetor is one of the most important parts of an engine. One of its tasks is to precisely control the mixing of fuel and air. It also controls the engine speed. In order to be able to function properly, its moving parts should always be kept clean. We will show you what really matters when cleaning a carburetor.

A Clean Carburetor – Still Important?

Today, carburetors are usually only installed in older cars without a catalytic converter. Most modern cars now have electronic injectors. However, they are still an important part of the engines of other vehicles and machines. These include:

  • lawn mowers and chainsaws
  • Scooters and mopeds with two-stroke engines
  • Oldtimer
  • Motorcycles
  • light aircraft

The carburetors of these engines should be cleaned regularly. This can be done manually or with professional cleaning machines. Ultrasonic cleaners for carburetors and other car parts can be found at www.palssonic.de.

What functions does the carburetor perform?

In order for a four-stroke engine to convert fuel into power, four work steps must be carried out. These are also called bars.

  • First stroke: intake
  • Second stroke: compression and ignition
  • Third bar: eject
  • Fourth bar: ignition

A carburetor basically consists of a tube with a constriction in the middle. When the piston lowers in the cylinder during the intake stroke to draw in new air, this happens via the carburetor. Due to the narrowing of the carburetor, the air flows faster, which reduces the pressure (Venturi effect).

What are the components of a carburetor?

A carburetor contains numerous individual parts. The carburetor can only fulfill its main task if these work together optimally. The largest component of the carburetor is a molded body made of light metal or Aluminium. Only small forces act on this stationary body, so the use of stronger metals would be unnecessary.

The moving parts of a carburetor, on the other hand, are made of steel or stainless steel. Certain small parts such as fuel nozzles or adjusting screws must be made of a metal that can be precisely machined. These parts must also be kept clean and free of debris at all times. Brass has the best properties to meet these requirements. It is therefore the metal of choice for fuel nozzles and small screws.

Clean the carburetor properly

The carburetor is often referred to as the nervous system of a gasoline engine. It is not uncommon for engine failures to be caused by a problem with the carburetor. The cleaning of the carburetor is therefore of particular importance.

To carry out a basic cleaning, first place the carburetor on a clean cloth and unscrew all parts. Be sure to keep the individual parts for each carburetor separate. Use a cleaning spray to clean all parts. Cleaning the nozzles is particularly important. Leave the spray on for half an hour and then blow dry with compressed air.

Carburetors usually contain several rubber sealing rings. Make sure you have a new set ready. Rubber seals can often be easily removed with a small screwdriver. When replacing, make sure that the new seals all remain clean in their intended recesses. Before reassembling a carburetor, lightly grease all rotating parts.

How often should you clean the carburetor?

There is no routine maintenance that needs to be performed on carburetors. There is therefore a rule of thumb that states that carburetors should be cleaned after they have driven 30.000 km. However, disassembling a carburetor can be very tedious. It is therefore advisable to only carry out an expansion if you identify specific problems with it. Otherwise you should have your workshop at the Inspection ask to do a cleaning.

Conclusion: Clean the carburetor

  • A clean carburetor will help keep your engine running properly, prevent corrosion and save you from costly replacements. It also ensures that the vehicle's efficiency in terms of fuel consumption and engine performance is maintained. Occasionally it may therefore be necessary to remove and carefully clean a carburetor. However, inexperienced car owners do not necessarily have to carry out this process themselves.

The following note is essential: For safety reasons, tuningblog recommends all repair, inspection and maintenance work exclusively to be carried out in a specialist workshop! Although our information is summarized to the best of our knowledge and belief, we cannot assume any liability for the content. All information is therefore "without guarantee".

Of course, that wasn't the end of it!

In this tuningblog category there are guides and instructions for common defects/repairs on the vehicle and for installing accessories/tuning parts. Our articles explain in a simple way common defects and the corresponding repairs and they also explain how the first signs of a defect become noticeable. In most cases, we also have initial clues to the repair instructions in our repair instructions approximate costs listed.

The goal of ourAuto Repair Guide“ is to create a head start in knowledge for the next visit to the workshop with initial tips. This may save you from tedious troubleshooting and you may even be able to do small things yourself. The same applies, of course, to the installation of accessories/tuning parts. Here, too, we would like to help with the implementation with instructions and tips. There are many other posts on this as well. Below is an excerpt of the last and HERE there are all previous instructions.
