For the Stihl historians on the forum . . . I know these questions of manufacture date usually get the response to check Acre's reference site, but our Internet filter here blocks Acres and won't allow me to view it. My first question is, what's the total span of manufacture for the 028? Was it 1977 to 1993? Secondly, if the 028 was and is the dependable workhorse that everyone claims, why did Stihl stop producing the saw? Thanks.
