Any chainsaw / firewood cutting experts on here?

Husqvarna and stihl are the only to buy. Worked as a line clearance tree trimmer for over 8 yrs. MS 250---perfect homeowner saw.
USE 2 STROKE MIX 50:1 WITH NON-ETHONAL PREMIUM, after 8 hrs run time adj idle after break in so chain doesn't rotate when at idle. Remember your PPE safety glasses, ear plugs, shoes and at least pants but chaps cant hurt. It only takes one mistake to get cut.
