• Gas tank cap. The gas tank cap covers the fuel tank and has a small vent in the cap that allows fuel to flow out of the tank to the carburetor.
• Sparkplug. The sparkplug provides the ignition spark that lights the fuel inside the cylinder to drive the piston.
• Flywheel key. The flywheel key mates the flywheel to the engine crankshaft.
