Sharpen it

As said sharpness is key, but if you are unsure or not been shown how to alter the mixture settings best to leave alone or get instruction. If you run the saw too lean it's possible to do major engine damage. You can refer to your manual for basic settings; typically 1 1/4 turns out on a Stihl on the H and L the other screw is idling. I have a feeling there is a video showing you how to do it either on Arbtalk or Youtube maybe someone will post you the link.

Re: how do you improve saw performance

a saw running lean will tend to overrev. a tacho can tell you the engine revs which when compared with the manufacturer's maximum revs figure will let you know whether it is running rich or lean.

not the 2 stroke mixture the actual air / fuel mix . when an engine is tuned i would expect it to run faster under load ie because it has more power but how do you set the mixture for a tuned engine because you wouldnt have the same airflow as a standard engine so the normal setting that were in the manual wouldnt be relevant or would they
