While with the Husqvarna 3120XP, the chain tensioner screw is located on the inside of the bar which makes its access a bit challenging.


IntelliCarb – Stihl MS 800 comes with an IntelliCarb Compensating Carburetor which is responsible for adjusting the air-to-fuel ratio. This way, there is a reduced airflow and less chance of air filters being clogged with the sawdust.

Moreover, with the help of this feature, the engine runs smoothly for a long time even in dirty and challenging conditions.
