i would agree buying new is best for any buisiness that dont need dn time,due to
equipment problems..but a new factor in the question is these new carbs..is every body going to have an stihl tech or the like ,,available to make these saws perform.id still buy new ,if i depended on saws for the bulk of my work..but this mite change the equation a bit.. jmo
for me my saws are good but several yrs old,with adjustable carbs so i enjoy ,keeping them rite..i am tho considering ,,
expanding to 2-3 trucks going out..
if i decide to take that plunge ,,it wont just be my saws but saws and other equipment,, for operators of varying skills..
that happens and ill go first class with the best i know to buy,, and dealer support backing them up.
