Which components should be removed from the carburetor during disassembly?

During the disassembly of a carburetor, it's important to remove components that are essential for accessing internal parts and ensuring proper cleaning and maintenance. The control lever, valve assembly, and fuel shut-off gasket are all critical components that can affect the carburetor's operation and performance.

The control lever allows for the adjustment of the throttle, which directly influences the engine's power and speed. Removing it helps in gaining better access for a thorough cleaning of passages that may obstruct fuel flow. The valve assembly is crucial as it controls the fuel mixture that enters the engine; regular inspection and cleaning of this component is necessary to maintain optimal engine performance. The fuel shut-off gasket also plays a role in preventing leaks, which can lead to improper fuel delivery or hazardous conditions. By removing these components, a technician can ensure that the carburetor is properly serviced and reassembled without any obstructions that could impair engine function.

In contrast, other options include components that either do not directly pertain to carburetor function (like the spark plug and muffler) or are not typically necessary for servicing during disassembly. This highlights the importance of focusing on parts directly related to fuel delivery and mixture when working with carburetors.
