Rover RS-436, 4 Stroke Sidepack Brush Cutter with 2T,80T Blade and Tap&Go Attachment

The four steps that this 4-stroke brush cutter machine follows are the same as those of a standard 4-stroke engine. The carburetor draws gasoline and air into the combustion chamber during the intake stroke, which starts the process. The air-fuel mixture in the cylinder bore is compressed by the piston during the compression stroke, which comes next. The compressed mixture is ignited by a spark plug during the power stroke, which produces high-pressure gasses that drive the piston downward and provide the machine power. Ultimately, one cycle of operation is completed during the exhaust stroke when the piston rises again and the spent combustion gases are released through the exhaust valve.
