2-stroke vs. 4-stroke: Which should you use?
If you or your users want to work outdoors easily and lightly in their daily life, the most suitable chainsaw is a 2 stroke gas chainsaw because it is lighter and can be easily moved in the direction you want. But a 4 stroke gas chainsaw is more powerful than a 2 stroke gas chainsaw. Not only does it have more power, but it also makes less noise and vibration, improving the user experience. At the same time, it is also accompanied by the characteristics of heavy weight and difficult operation.
