What You'll Learn
Locating the carburetor
To locate the carburettor on your Troy-Bilt riding lawn mower, start by opening the hood and looking on the side of the engine, where it is usually found. The carburettor is connected to the air filter, so you can follow the air filter to find it. Once you've located the carburettor, you'll need to remove it from the engine. Start by disconnecting the fuel line and then unscrewing the bolts that hold the carburettor in place.
You can then begin to clean the carburettor. First, carefully disconnect any fuel lines or throttle cables that are attached to it, noting how these connections are made so that you can reattach them correctly later. Once everything is disconnected, gently lift the carburettor out of its housing, being careful not to spill any fuel or drop any small parts.
With the carburettor removed, you can now clean it thoroughly using the appropriate cleaning solution. Use a carburettor cleaner spray to remove any built-up dirt or grime, and make sure to clean all the small parts, including the jets and passages. You can also use a small brush to clean the main body, jets, and float bowl.
After cleaning, reassemble the carburettor and reinstall it on the engine, making sure to tighten the bolts to secure it in place. Finally, attach the fuel line and start up your mower to test it out. You should notice improved performance and smoother operation.

Disconnecting the fuel line
To disconnect the fuel line of your Troy-Bilt mower, start by locating the carburetor. It is usually found on the side of the engine and is connected to the air filter. Once you've found it, you can begin to remove it by first disconnecting the fuel line.
Unscrewing the Clamp

Absorbing Residual Fuel
Use a shop towel or rag to absorb any residual fuel left in the fuel line to prevent spills. If your fuel tank still has fuel in it, hold the fuel line upward to prevent unintentionally draining it.
Draining the Fuel Line
Place the end of the fuel line into an approved fuel container to drain any remaining bad fuel. You can use a pulling and twisting motion to remove the fuel line from the fuel filter.
Once the fuel line is disconnected and drained, you can proceed with cleaning the carburetor and other components.
