Checking the Air Filter

Expect plenty of debris and dirt to kick up while cutting grass on your lawn with a riding lawnmower.

Dirt would never enter the engine via the carburetor if the air filter were clean and functioning optimally.

For this reason, it is the first place you ought to check before cleaning the rest of the carburetor. Cleaning the air filter is a simple maintenance measure that improves performance substantially. To clean the air filter, you would have to switch off the engine first before disconnecting the spark plug. Next, you should:

  • Remove the cover of the air filter
  • Use compressed air to clean the foam of the pre-cleaner
  • Remove and discard old paper filter
  • Install new air filter
  • Replace the cover of the air filter
  • Reconnect spark plug wire

Additionally, you ought to be ready with all the appropriate cleaning tools. First is a screwdriver, which is essential for removing screws. Rags are also critical for wiping the dirt that could be either on or inside the carburetor. A flashlight or headlamp is necessary for seeing the darkest parts of the carburetor.

Get a headlamp since it allows you to work hands-free. An aerosol cleaner is equally important in this type of work. Do not just use any aerosol cleaner that you get. Instead, look for the most appropriate one for a fuel-power, electrically charged running machine such as the riding lawnmower. Be ready with an air-compressor gun as well.

Examine All Connections

The next step in boosting your knowledge on how to clean a carburetor on a riding lawn mower is to examine the various connections featured in the machine. Here, the most important connections to watch out for are those running from the throttle all the way to the choke plates. The reason for this is they are capable of sticking together when dirt permeates this part of the mower. Sticky connections are a nightmare. However, it is worth mentioning that connections are not limited to wires alone. In this regard, pay special attention to the screws, which are notorious for loosening because of the constant vibration, wear and tear.

Using Special Carburetor Cleaner

Next, look for a special carburetor cleaner to use. Specialized cleaners are highly effective at eradicating stubborn deposits within the carburetor. Some of these deposits are capable of clogging airways and fuel passages. Cleaners are the best at improving the performance of the carburetor and the riding lawnmower too.

The market is full of various types of carb cleaner sprayers. Therefore, take your time researching the best one. In some cases, you might also need ultrasonic carburetor cleaners. Specialized cleaners are great because they eliminate the need for removing the carburetor from the engine.

Check Carburetor Settings

Nevertheless, it is also understandable if you are unable to read or interpret the information displayed on the settings. In such instances, a good move would be to take the carburetor to your local mechanic or repair service store.

The technicians at the store are highly trained and experienced; thus, the best at grasping what the settings mean. They would help you identify all issues and problems that your carburetor has developed.

Can you tell if the carburetor needs a bit of cleaning? Well, the things to look out for are not too complex. For starters, when the engine appears weaker and the performance levels drop significantly, then you would know that the component needs cleaning. Additionally, watch out for the emission of black smoke.

A carburetor that cannot stop overheating deserves thorough cleaning too. Furthermore, the moment it starts shutting down suddenly or starting jumpily, then you should not waste any more time. Jumpy starts signal faulty internal parts. Instead, get the necessary tools as fast as possible to start cleaning it thoroughly.
