How to Use Carburetor Cleaner on a Small Engine?

Small Gasoline Engine Can't Start Properly? What's the Reason?

It's likely that the carburetor is clogged! When the engine cannot be started according to the correct starting method, you should quickly check the air filter (whether it is clogged), spark plug (whether it is ignited), gasoline (whether there is gasoline in the fuel tank and carburetor oil cup), compression (whether compression can be felt), etc. If the above items are normal, then you should suspect whether the engine carburetor is clogged. Most carburetor problems are caused by dust particles, gasoline gelling and other impurities that are blocked in the carburetor nozzle. The main nozzle of the carburetor is an area that is particularly prone to being clogged by impurities and colloids.

You can remove the engine carburetor, disassemble the oil bowl, use the carburetor and choke cleaner spray to align the main nozzle, needle valve and idle speed metering hole and other holes and contact points of the carburetor, and press the button on the cleaning liquid pressure bottle to spray cleaning liquid to clean and wash the carburetor. After cleaning, install the carburetor back to the engine.

Then, add gasoline to the tank and pull the starter rope according to the start-up operation. If the start is successful, then congratulations! Problem solved. If the engine runs (even if it only hums once) but then stalls, you should be aware that there may be something wrong with the engine's fuel supply system. You can try to start it again. If it still won't start after three attempts, you need to do a full engine diagnosis.

Should the Carburetor Be Repaired or Replaced?

The first thing you need to do is check if the carburetor is corroded. If it is corroded, you must replace it with a new one. If the carburetor is not corroded and can be used normally after cleaning, then there is no need to replace the carburetor.

Good Maintenance Habits Can Prevent Carburetors from Getting Clogged

Regularly replacing the air filter and using gasoline that has not deteriorated can prevent gasoline from deteriorating and gelling and dust impurities from clogging the carburetor.

How to keep the carburetor clean?

• Step 1: Regularly replace the air filter Check and replace the air filter regularly to ensure that the air entering the carburetor is clean and free of impurities.

• Step 2: Make sure to use non-deteriorated gasoline Use fresh gasoline from a regular gas station, which has fewer impurities and will not deteriorate and gel quickly. Before storing the equipment for a long time (more than 30 days without using the engine), drain the gasoline from the tank and carburetor. Alternatively, add Briggs & Stratton's gasoline stabilizer to the tank and let the engine run for 1-2 minutes before shutting off before storing.

• Step 3: Use carb choke & parts cleaner regularly to remove deposits, blockages and impurities Considering that small engines often appear in dusty, weedy and debris-filled working environments, over time there will be small amounts of impurities and deposits in the passages within the carburetor, which also require maintenance. With a carburetor cleaner specifically designed for small engines, you can quickly and easily deal with these problems, often without even removing the carburetor from the engine. Common carburetor cleaners come in spray cans and can be used to regularly clean the inside and outside of the carburetor.

To Use Carburetor Cleaner on a Small Engine, Follow These Detailed Steps:

Preparation:

Open the hood, carefully remove the air filter, and take out the paper core that filters the air.

Start and warm up:

Start the engine and gradually increase the throttle to stabilize the engine speed at 5000 rpm to ensure that the cleaner can effectively reach every corner.

Connect the cleaner:

Use a special extension hose to accurately connect the carburetor choke cleaner to the nozzle. Make sure the nozzle is aimed at the key area of the carburetor.

Spray the cleaner:

Press the nozzle to let the cleaner spray into the carburetor. The cleaner will quickly break down and remove carbon deposits and dirt.

Observation and cleaning:

Observe whether the stains are discharged from the exhaust pipe as the engine runs, taking away the burden of the past.

Subsequent maintenance:

After each cleaning, check whether the carburetor has a significant cleaning effect, and perform maintenance regularly as needed.
