How to Clean Carburetor on Troy Bilt Lawn Mower?

How to Clean Carburetor on Troy Bilt Lawn Mower?

Step 1: Try to start the lawn mower

You can use this as a quick test to see if the carburetor is clogged. If the mower will not start, the carburetor is a likely culprit. If the engine tries to start but sputters and dies, there is another issue with your mower that you will want to address.

While starting the engine, keep an ear out for unusual noises. If the engine runs poorly or emits excessive noise, it may be an indication that the carburetor needs to be cleaned.

If you can start the mower, but it dies quickly, the problem is not with the carburetor. Rather, the fuel is likely not getting to the carburetor.

In this case, check the fuel line for any kinks that may be blocking the flow of fuel. If the fuel is flowing freely, the problem may be a bad fuel pump.

Step 2: Check the Carburetor’s Gas

Before you begin the process of cleaning the carburetor, make sure that the gas in the tank is clean. Old fuel can clog a carburetor and cause poor performance. If you have fuel in the tank that is more than three months old, drain the tank and replace the fuel. If you do not wish to replace the fuel, use a fuel cleaner to make the old fuel usable again.

Step 3: Extract the Carburetor

If you have confirmed that you have fresh gas in the carburetor, the carburetor needs to come off the engine to clean it. You can use a wrench to loosen the clamp holding the carburetor to the engine. Once the carburetor is loose, remove the clamps holding the carburetor in place.

Then, pull the carburetor off the engine. If the carburetor is extremely clogged, you may have to apply pressure to break it loose.

Step 4: Confirm the Corrosion

If your carburetor came off the engine clean, there is no reason to worry. If the carburetor is completely caked in rust, you may need to clean the carburetor thoroughly and treat the metal with a corrosion inhibitor.

If you find that the carburetor has corrosion on it, you will need to thoroughly clean the carburetor before you can use it again.

Step 5: Put Carburetor on Workbench and Start the Rebuilt

Once the carburetor is clean, you can put it on the workbench and take a look at all the mechanisms inside it. You can use a small brush to get into the nooks and crannies of the carburetor and remove any remaining debris.

Once you have everything clean and inspected, it’s time to rebuild the carburetor.

Step 6: Clean the Mechanisms

While there are many different parts that comprise a carburetor, two of them are more likely to get clogged:

The float assembly and the needle and seat. Use a wire brush to brush off the float assembly and make sure the float pin is clean. The float assembly affects how much fuel is held in the carburetor.

 If it is clogged, the carburetor will not be able to hold the right amount of fuel and your mower will not run properly. Next, focus on the mechanisms that meter the fuel flow. The needle and the seat are normally rubber, and they can get clogged with debris. Use a small brush to clean these parts and make sure that they are not clogged.

Step 7: Reassemble the Mechanisms

When you have all the mechanisms clean, you can reassemble the carburetor. Put the float assembly back in the carburetor and make sure that the needle and seat are installed correctly. You can test the carburetor to make sure it is working properly by adding fuel to the carburetor and trying to start the engine.

If the engine starts and runs smoothly, you have successfully cleaned the carburetor and you can put it back on the mower. When you are finished cleaning the carburetor on your Troy Bilt mower, make sure to keep it clean and free of debris to keep your mower working at its best.

Conclusion:

Carburetors can become contaminated with plant life and other undesirable compounds that affect the performance of your gas-powered lawn mower. Depending on the type of fuel you’re using, carburetor cleaning can be as simple as rinsing with a bit of fuel, but for the best results, it’s important to clean your carburetor more thoroughly. The first step to carburetor maintenance is making sure that it’s relatively clean.

It’s important to understand that you can’t just pour some cleaner into the carburetor, as this can splash fuel into the engine.

Carburetors typically have a small hole at the bottom of the unit, which is used to pour in the cleaning solution. If this hole is currently blocked, then it could be time to replace the carburetor.
